Compact structure of starter
First Claim
1. A starter comprising:
- a motor that produces torque for starting a given object;
an output shaft connected at an end thereof to a clutch, the motor transmitting torque to the output shaft through the clutch;
a pinion carrier including a pinion and a holder that are fit on an outer periphery of the output shaft, the pinion and the holder being rotatably joined together;
a shift lever; and
an electromagnetic actuator which, when energized, produces a magnetic attraction acting on the shift lever to shift the pinion carrier to bring the pinion into engagement with a ring gear joined to the object to transmit the torque to the object,wherein the holder of the pinion carrier holds the shift lever to establish a connection between the shift lever and the pinion, the holder being made of material smaller in specific gravity than the pinion.

Abstract
A starter which may employed in starting an engine is provided. The starter includes an electromagnetic actuator and a pinion carrier. The pinion carrier includes a pinion and a holder. The holder retains a shift lever and transmits movement of the shift lever, as achieved by a magnetic attraction produced by the electromagnetic actuator, to the pinion, thereby shifting the pinion into engagement with a ring gear joined to, for example, an engine. The holder is made of material smaller in specific gravity than the pinion. Specifically, the holder is lower in mass or weight than the pinion, thereby permitting the magnetic attraction required to shift the pinion carrier through the shift lever to be decreased. This permits the electromagnetic actuator to be decreased in size.
