PURPOSE:To press-form a steel plate to improve productivity by fitting a clutch power shaft slidably to a cylindrical part formed at the center parts of fly wheels and brackets through a bearing. CONSTITUTION:A ball bearing 11 at the reverse load side of a clutch power shaft 10 is movably supported in the axial direction at the cylindrical part 6a of a fly wheel 6 mounted on a motor power shaft 5, and only the ball bearing 12 at the load side of the shaft 10 is supported by a cylindrical bearing 13, and the bearing 13 is supported by the cylindrical part 15 of a clutch bracket 14'. Accordingly, the bearing 13 is sufficient to support only the bearing 12 at the load side, and the length thereof becomes about 1/2 of the conventional cylindrical bearing. Accompanied by said mechanism, the cylindrical part 15 of the bracket 14' supporting the bearing 13 becomes less than about 1/2 as compared with the conventional one. As a result, a clutch bracket is press-formed from a steel plate to improve the productivity. |
