摘要： A starter for an engine is equipped with a planetary gear speed reducer, a restraining mechanism, and a shock absorber which is made up of a rotary disc, a stationary disc, a case, and a load applying mechanism. The load applying mechanism applies a load to the stationary and rotary discs to develop a given degree of friction therebetween. When an excessive torque acts on the rotary disc through the internal gear, the shock absorber induces the rotary disc to rotate against the given degree of friction to absorb the torque to eliminate a physical impact to be exerted on the planetary gear speed reducer. The restraining mechanism restrains the load applying mechanism from moving in a radius direction of the internal thread to avoid undesirable engagement of the load applying mechanism with the internal thread, thereby ensuring the stability in applying the load to the stationary and rotary discs.

摘要： A brush holder is held between a yoke of a starter motor and an end frame made of resin. The brush holder has an engaging guide portion projecting axially therefrom and engaging the yoke and the end frame and a projected peripheral portion projecting outside from peripheral surfaces of the yoke and that of the end frame. The brush holder contacts the yoke and the end frame at cylindrical surfaces thereof and surfaces perpendicular to the cylindrical surfaces. This construction allows the brush holder to be prevented from loosening, thus improving the vibration proof and durability of the brush holder. Further, the brush holder contacts the yoke and the end frame at the cylindrical surfaces thereof and the surfaces perpendicular to the cylindrical surfaces, thus dissipating the heat of a brush through the brush holder and the yoke more efficiently.

摘要： A rotational torque of an electric motor of a starter is transmitted to an output shaft having a pinion gear engaging with a ring gear of an internal combustion engine via a one-way clutch. A tube forming a clutch-inner and the output shaft are spline-coupled to allow the output shaft to reciprocally move in the axial direction while transmitting the rotational torque of the tube to the output shaft. The output shaft is slidably supported by a supporting portion formed at a front end of the tube. To establish air communication between an inside space of the tube and an outside space, an air passage is formed either in the supporting portion or on the output shaft. Pressure changes in the inner space due to reciprocal movement of the output shaft are suppressed by air communication through the air passage, and lubricant in the tube is well retained therein.

摘要： A starter for cranking an internal combustion engine includes an electric motor, a planetary gear speed reduction device for reducing a rotational speed of the electric motor and an excessive-torque-absorbing device. The excessive-torque-absorbing device is composed of plural rotatable disks that form an internal gear of the speed reduction device, plural fixed disks and a disk spring. Both disks are alternately laminated and pressed in the laminated direction by the disk spring. When a rotational torque of the electric motor to be transmitted to a pinion gear of the starter exceeds a predetermined level, slippage occurs between the rotatable disks and the fixed disks, and thereby the excessive torque is absorbed.
