Abstract
A starter is composed of an output shaft, a pinion having an outer gear slidably disposed on the output shaft, a planetary gear-type speed reduction mechanism, a one-way clutch having clutch outer linked with the planetary gears, a clutch inner linked with the output shaft and a plurality of rollers disposed between the clutch outer and clutch inner, and an alignment member, disposed around the one-way clutch. The alignment member restricts deviation of axis of the clutch outer from the axis of the output shaft.
Claims5
A starter comprising:
- a case member;
- a drive motor disposed in said case member;
- an output shaft;
- a pinion having an outer gear and being slidably disposed on said output shaft;
- speed reduction mechanism, disposed in said case member, including a sun gear linked with said drive motor, a planetary gear, an internal gear, and a supporting pin for supporting said planetary gear;
- a one-way clutch having a clutch outer member linked with said supporting pin, a clutch inner member linked with said output shaft, and a plurality of rollers disposed between said clutch outer member and clutch inner member;
- and
- an alignment member, disposed in said case member around said one-way clutch, to provide a prescribed gap between an inner periphery of said alignment member and an outer periphery of said clutch outer member in order to restrict a radial displacement of said one-way clutch from the axis of said output shaft.
