摘要： A starter for cranking an internal combustion engine includes an electric motor for driving a pinion gear of the starter. The rear end of the electric motor is covered with a rear end frame having a bearing holder formed thereon. To protect the bearing holder from external force applied to the rear end frame, a rear end cover having an upper plate is connected to the rear end frame. The upper plate of the rear end cover is positioned to form a certain space between the rear end frame and the upper plate. The rear end cover may be connected to the rear end frame by utilizing bolt heads of a pair of through-bolts fastening the electric motor to a front housing and the rear end frame.

摘要： A starter for an engine, having a ring gear includes an output shaft for slidably holding a pinion gear engageable with the ring gear, a housing having an opening portion that enables the pinion gear to engage with the ring gear when the pinion gear advances, a cover having a shutter, a front wall and a side wall for sliding together with the pinion gear. The shutter opens the opening portion when the pinion gear advances and shuts the most part of the opening portion when the pinion gear retracts. The front wall is provided to cover at least half of a front portion, which faces to the ring gear, of the pinion gear. The side wall is extended from the front wall in a direction parallel to an axis of the output shaft to cover at least half of the gear tooth periphery in a circumferential direction of the pinion gear. When water carried by the rotating ring gear comes to the opening portion when the pinion gear rotates with the ring gear, most of such water is blocked by the gear tooth. Furthermore, the rest of water is blocked by small gaps between the pinion gear and the cover. When the pinion gear is disengaged from the ring gear, the shutter closes most of the opening portion. Therefore, most of water carried by the rotating gear is blocked by the shutter. Even if water enters inside of the housing through a small gap between the opening portion and the shutter, water is blocked by small gaps between the pinion gear and the cover.
