Claims

[Scope of Claim for Utility Model Registration] (1) In a starter for a motorcycle, etc., which is equipped with an excessive torque absorption mechanism, a pinion gear shaft that is rotatably fitted into the rotor shaft of a starter motor, and a front bracket are provided. The inner rotor shaft has a friction disk spline-coupled by fixing a dry friction material to an appropriate location, and an elastic pressing member that presses the friction disk toward the pinion gear shaft. A pinion gear is attached, and a torque transmission flange is formed integrally with the pinion gear shaft at the other end, and the torque transmission flange side is placed inside the front bracket, and the torque transmission flange and the dry friction material are fixed. A starter characterized in that a torque limiter is formed by contact with a friction disk, and torque is transmitted. (2) The torque limiter is formed by the contact between the flange of the pinion gear shaft and a friction disk that is integrally formed with a bush that is press-fitted onto the rotor shaft in the starter case, and the torque is transmitted through the rotation of the rotor shaft. The starter according to claim 1, wherein the starter is pressed in the direction of the friction disk by an elastic pressing member fitted into the side end. (3) The pinion gear shaft is supported by a bearing fitted into the front bracket, and the outside and the inside of the starter motor are sealed by an annular seal member fitted close to the bearing. A starter as set forth in either claim 1 or 2 of the utility model registration claim, characterized in that:
