Claims

[Claims for Utility Model Registration] (1) A starter for starting an engine that transmits engine power to wheels via a wet clutch, comprising a starter housing, an electromagnetic switch, and an electromagnetic switch installed in the housing. , a movable lever that is moved by the electromagnetic switch; a motor that has an armature shaft with a gear and is activated by the electromagnetic switch; and a clutch gear part that is housed in the housing and constantly meshes with the clutch inner ring and the gear shaft. a clutch having a clutch outer ring; at least one pair of bearings rotatably supporting the clutch inner ring with respect to the housing; In a starter comprising a pinion shaft that can slide in a direction and mesh with a ring gear, the bearing on the wet clutch side of the bearing is a sealing bearing, and there is a gap between the bearing and the housing, and further between the bearing and the housing. A starter characterized in that an O-ring is interposed between the inner races of the clutch, and an oil seal is interposed between the non-spline portion of the pinion shaft and the inner race of the clutch. (2) The starter according to claim (1), wherein each spline of the pinion shaft and the clutch inner ring is a helical spline. (3) The pinion shaft integrally has a spring seat that is slidable in the axial direction with respect to the clutch inner ring, and is disengaged from the ring gear by a spring interposed between the spring seat and the clutch inner ring. Claim No.
The starter described in (1).
