An engine starter drive device having a sleeve member slidably and mounted for rotation on a power shaft of a motor is disclosed. The sleeve is connected to a mounting shaft which is mounted adjacent to the power shaft. A pinion gear is mounted on the mounting shaft. A driving clutch member is mounted on external helical splines formed on the sleeve. The driving member is connected in one direction of rotation to a driven clutch member by axially extending clutch teeth. The driven member is connected to the pinion gear for rotation therewith. Between the driving and driven clutch members is a centrifugal separator member which moves the driving clutch member away from the driven clutch member above a predetermined rotational speed. The pinion gear thus is mounted on that portion of the mounting shaft that is isolated from the outer environment. |
