<p><P>PROBLEM TO BE SOLVED: To reduce the size of power unit with a built-in clutch operation auxiliary device for reducing an operation force of a clutch lever. <P>SOLUTION: The clutch operation auxiliary device 70 is equipped with: a push shaft 39; a bearing plate 14c for supporting the push shaft 39; and a first rotation plate 51, rotatably supported by the bearing plate 14c and connected with a clutch wire 43, for sliding the push shaft 39 by rotating. The first rotation plate 51 is geared with a second rotation plate 52. The second rotation plate 52 is pin-connected with a spring unit 54 for providing an assisting force in a direction to block a friction clutch. The spring unit 54 is rockably supported by a mounting seat 14d. The spring unit 54 is mounted so that when viewed from a shaft direction of the push shaft 39, an expansion/contraction direction S2 of an auxiliary spring 67 does not pass through a rotation center 39a of a pressure plate 37. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
