<P>PROBLEM TO BE SOLVED: To stably hold an operation lever at prescribed turning positions independently of the tension of a wire, and to reduce an operation amount. <P>SOLUTION: A lever operating device 90 includes a main clutch lever 54, a main clutch, a holding mechanism 80, and the like. The holding mechanism 80 includes: a first supporting member 81 axially supported by a turning shaft 66 in a manner turnable integrally with the main clutch lever 54; a slide shaft member 83 slidably inserted through a cam hole 81c opened through the first supporting member; a second supporting member 82 on whose one side the slide shaft member is erected and whose other side is axially supported by a turning shaft 87; and a torsion spring 84 having one end engaged with a base plate 63 and the other end engaged with the slide shaft member and performing the biasing so that the distance between both engagement parts are expanded. When the main clutch lever is switched to an off-position or an on-position, the slide shaft member crosses a virtual line segment R connecting the turning shaft 66 and the turning shaft 87, and engaged by an engagement part provided at the cam hole so that the further turning is limited. <P>COPYRIGHT: (C)2012,JPO&INPIT |
