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.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.COPYRIGHT: (C)2012,JPO&INPIT【課題】ワイヤーの張力に依存せずに操作レバーを所定の複数の回動位置に安定的に保持し、かつ、操作量を低減する。【解決手段】レバー操作装置90には、主クラッチレバー54、主クラッチ、及び保持機構80等が具備され、保持機構80には、主クラッチレバー54と一体的に回動可能に回動軸66に軸支される第一支持部材81と、第一支持部材に開口したカム孔81cに摺動自在に貫装される摺動軸部材83と、一側に摺動軸部材を突設して他側が回動軸87に軸支される第二支持部材82と、一端がベースプレート63に係合され、他端が摺動軸部材に係合されて、両係合部間の距離が広がるように付勢するネジリバネ84と、が備えられ、主クラッチレバーを切位置と入位置に切り替えるときに、摺動軸部材は回動軸66と回動軸87を結ぶ仮想線分Rを横切り、カム孔に設ける係合部で係合されてそれ以上の回動が規制される構成とした。【選択図】図8
