摘要： An electromagnetic switch includes a contact holding member connected to a plunger in order to hold a first movable contact. The contact holding member is disposed outside a switch case covering a periphery of an excitation coil. A return spring pushes the plunger back in the opposite direction to a fixed iron core through the contact holding member when electric power supply to the excitation coil is stopped. The return spring is disposed outside the switch case. In this structure, a spring holding portion does not need to be disposed in the fixed iron core and the plunger. Therefore, an area where the fixed iron core attracts the plunger can be increased, so that an attraction force can be increased.

摘要： In a starter, an electromagnetic switch is mounted to a seating. A lead wire of an exciting coil is led to an outside of a switch case by a coil-leading portion and is connected to a male terminal, which is fixed to the coil-leading portion by welding. The coil-leading portion is integrally provided with an end plate portion of a bobbin around which the exciting coil is wound. The coil-leading portion passes through and projects from a bottom surface of the switch case to the outside. A metal member, in a form of a plate, is insert-molded in the seating. A 50 terminal is provided on an end of the metal member and a female terminal is provided on an opposite end of the metal member. When the electromagnetic switch is mounted to a predetermined position of the seating, the female terminal engages with the male terminal.

摘要： A starter solenoid switch according to the present invention includes a first and a second set of contacts that are disposed between a battery and a starter motor in parallel with each other. The first and the second sets of contacts are so configured that the second set of contacts is closed to supply a lighter electric current to the starter motor before the first set of contacts is closed to supply a heavier electric current to the same. The second set of contacts is composed of a second fixed contact and a second movable contact, one of which includes a low-resistance portion at one end thereof and a high-resistance portion that contains more carbon than the low-resistance portion. The low-resistance and the high-resistance portions are serially disposed along a conducting path of electric current from the battery to the starter motor, thereby ensuring reliability of the starter solenoid switch.

摘要： A pinion gear of a starter is engaged with a ring gear of an internal combustion engine by restricting rotation of the pinion gear while driving a motor at a low speed. After the engagement is established, the motor is driven at a full speed by supplying a full current, thereby cranking up the engine. After the engine is cranked up, the engagement between the pinion gear and the ring gear is released. In order to prevent the motor from being driven at the full speed before the pinion gear fully engages with the ring gear, rigidity of a crank bar for restricting the pinion rotation is made sufficiently high to generate a spring-load that exceeds a force for driving a plunger that closes a switch for supplying the full current.

摘要： A carrier portion includes a side wall portion which restricts shifting of rollers in the axial direction. The side wall portion has a receiving hole formed at a radial central region. A clutch outer, integrally formed with the carrier portion, is rotatably supported via a bearing by a front axial end portion of an armature shaft. The bearing is fixed by press fitting on an inner cylindrical surface of the receiving hole. A tapered portion, provided at an edge of the front axial end portion of the armature shaft, is a guide surface for guiding the armature shaft into the bearing. The length of the front axial end portion is determined in such a manner that the side surface of a sun gear can contact with the side surfaces of the planetary gears in the axial direction after the tapered portion entirely enters inside the bearing.

摘要： In a commutator motor, a brush holding device includes a plurality of brush holders and a substantially annular holder plate. Each of the brush holders includes a holder frame, which receives a pair of brush and spring, and a bottom plate having two opposite side portions. The holder plate is disposed around a commutator and has a major surface on which a plurality of pairs of guide walls are formed; each pair of the guide walls defines a pair of grooves. The side portions of the bottom plate of each of the brush holders are respectively fit in a corresponding pair of the grooves defined by the guide walls. Each of the brush holders has a radially outer end that abuts an inner surface of a side wall of an end frame, whereby radially outward movement of each of the brush holders is restricted by the end frame.

摘要： Provided is a heater power control circuit which switches on/off a voltage signal supplied from a direct-current power source to control a power of a heater by controlling a voltage applied to the heater. The heater power control circuit includes a voltage smoothing circuit that is disposed between the heater and a switching circuit which switches on/off a voltage supplied from the direct-current power source. The voltage smoothing circuit converts the voltage into an analog voltage signal by smoothing a voltage signal obtained by switching on/off the voltage.

摘要： An electromagnetic switch has a shaft and a movable contact member slidably supported by the shaft. The shaft is moved with a plunger when an electromagnet is formed of an electromagnetic coil receiving an electric current and attracts the plunger. The movable contact member is moved with the plunger and connects fixed contact members with each other to turn on the switch. The shaft has a shaft body and a projection projected from the shaft body. The movable contact member has a hole. The projection is inserted into the hole to pass through the hole, and the movable contact member is disposed on the shaft body. Then, the movable contact member is rotated so as to engage the projection with the movable contact member. Therefore, the projection prevents the movable contact member from coming out of the shaft.

摘要： A pinion gear of a starter motor is driven into engagement with a ring gear of an internal combustion engine by a driving lever having a leaf spring upon energization of an electromagnetic actuator. The leaf spring of the driving lever is coupled to a connecting member of a plunger of the electromagnetic actuator. The connecting member includes a surface engaging with an engaging portion formed at one end of the leaf spring. A center portion of the engaging surface is projected toward the leaf spring, so that the engaging portion of the leaf spring always contacts the engaging surface at the center of the engaging surface, even if the leaf spring is slantedly coupled with the connecting member.
