<p>A switch lever (3) is rotatably supported on first and second cases (1, 2) and is held in one of three positions of right and left ON positions and neutral position by cooperation of a cam face (9) formed on the first case with an actuator provided on the switch lever. On the inside bottom surface of the second case, first and second support pins (6b, 11) are provided upright. A first lever member (6) is rotatably supported on the first support pin and a second lever member (7) is rotatably supported on a support pin formed upright on the forward end of the first lever member. In the second lever member are formed first and second long holes (7a, 7b), in which the support pin and the second support pin are fitted. A torsion spring (8) is provided to press the second lever member in the longitudinal direction of these long holes. When the switch lever is turned to right or left turn position, the second lever member is moved forward into the path of rotation of a cancel projection by the force of the torsion spring, turning the second lever member. The first lever member is turned in interlock with the second lever member, thereby automatically returning the switch lever to neutral position. <IMAGE></p> |
