Problems solved by technology

[0003] In order to prevent the engine from vibrating to generate noise, the transmission case body is connected to the crankcase through an elastic gasket, but in such a transmission case case, as the above-mentioned prior art, the transmission case body is connected to the crankcase through an elastic support member. When the pinion bracket is connected to the crankcase, the pinion bracket cannot be firmly supported on the crankcase, and it is difficult to improve the durability of the pinion support shaft

Abstract

Provided is a pinion-shaft support structure for starter in a power unit which can firmly fix a pinion holder to a crankcase thereby ensure stable supporting of the pinion shaft. In a case where one end of a pinion shaft (45) supporting a pinion (46) movably in an axial direction is supported with a bearing boss (48) which faces the inside of the transmission case (23) and which is formed in a crankcase (10), and the other end is supported with a boss (50a) of a pinion holder (50) provided in the transmission case (23), the pinion holder (50) is integrally fixed to the crankcase (10) with plural bolts (51 and 52) surrounding the boss (50a) at equal intervals.

Description

technical field [0001] The invention relates to a support structure for a pinion support shaft for a starter on a power unit. The power unit is interposed with an elastic gasket, and a side wall of a crankcase of an engine cooperates to form a gearbox case for accommodating a transmission. The gearbox case is connected to the one side wall, and the pinion support shaft is connected to the output shaft of the starter motor supported on the crankcase, and supports a movable shaft that can engage and separate from the ring gear of the engine. One end of the pinion support shaft can be freely rotatably supported on a side wall of the crankcase facing the inside of the above-mentioned gearbox case, and can be freely rotated by the pinion bracket arranged in the above-mentioned gearbox case. ground supports the other end of the pinion support shaft. Background technique [0002] In the past, the support structure for the pinion support shaft of the starter on such a power unit, a...
