摘要： A motor includes a motor portion and a speed reducing portion. In the motor portion, a brush holder that holds a feeder brush for feeding electric power to a commutator is arranged at an opening of a yoke. The speed reducing portion has a speed reducing mechanism, which is arranged in a gear housing. The speed reducing mechanism outputs drive force produced by a rotary shaft of the motor portion with the rotating speed of the rotary shaft reduced by the speed reducing mechanism. A brush holder includes a support pillar projecting toward the gear housing and an urging member that urges the feeder brush against the commutator. A positioning portion for positioning the brush holder with respect to the gear housing in a direction perpendicular to the axial direction is formed at a distal end portion of the support pillar.

摘要： Each of a plurality of brushes is tilted relative to an imaginary plane that is perpendicular to a rotational axis of an armature and is placed on one axial side of a brush holder, at which an interior of a yoke housing is located. A radial inner end part of each brush has a slide contact surface, which is generally parallel to the rotational axis of the armature and slidably contacts an outer peripheral surface of a commutator. At least a portion of the slide contact surface of each brush is axially disposed outside of an opening of the yoke housing.

摘要： A holder-side connecting portion 10c provided on a brush holder 10 and a connector-side connecting portion 16b provided on a connector portion 16 are electrically and mechanically connected with each other. The holder-side connecting portion 10c and the connector-side connecting portion 16b are clamped between a yoke housing 4 and a gear housing 21. For this reason, the connecting portions 10c and 16b for connecting the brush holder 10 and the connector portion 16 are prevented from being externally exposed. As a result, the insulation of the connecting portions 10c and 16b can be secured without complicating the construction of the connecting portions 10c and 16b by applying a special seal or the like to the connecting portions 10c and 16b.

摘要： A control circuit member provided in a motor is disclosed. The motor includes a motor main body having a rotary shaft and a gear housing integrated with the motor main body. The control circuit member includes a circuit substrate on which a rotation detecting element is mounted and a substrate support member. The circuit substrate is accommodated in a circuit accommodating portion in the gear housing. The substrate support member supports the circuit substrate inside the circuit accommodating portion. The control circuit member is configured to be insertable into the circuit accommodating portion along the axial direction of the rotary shaft. The circuit substrate is configured to be arrangeable inside the circuit accommodating portion while being inclined with respect to the axial direction of the rotary shaft, so as to cause the rotation detecting element to approach the detector magnet.

摘要： A clutch including a drive shaft, drive side rotation body, driven shaft, driven side rotation body, clutch housing, and lock member is disclosed. During non-rotation of the drive side rotation body, when the driven side rotation body is rotated, the lock member is pushed by the driven side rotation body and moved outward in a radial direction thereby bringing the contact portion into contact with the inner circumferential surface of the clutch housing. During rotation of the drive side rotation body, the drive side rotation body pushes a drive side cam surface in the rotation direction, and the drive side cam surface acts to move the lock member inward in the radial direction and push the lock member against the driven side rotation body. Thus, the lock member is sandwiched between the drive side rotation body and the driven side rotation body thereby coupling the drive side rotation body and the driven side rotation body with the lock member to be integrally rotatable.

摘要： A gear housing accommodates a worm shaft. A brush holder includes a base member and a retaining member loosely fitted to the base member. The base member is located between the gear housing and the retaining member. The retaining member retains a first brush and a second brush. The retaining member has a pair of positioning poles, and the gear housing has a pair of positioning projections. The positioning poles and the positioning projections are engaged with each other so as to prevent the retaining member from being moved in a direction perpendicular to the axial direction of the rotary shaft.

摘要： A bonding structure of a valve seat has a port opening of a metallic head and an annular metallic valve seat insert. The valve seat insert includes an outer reduced diameter surface on its outer circumference. The material of the valve seat insert is harder than that of the head. The head plastically deforms upon pressing the valve seat insert toward the head. The deformed metal occupies any gap around the outer reduced diameter surface.
