Claims

[Scope of utility model registration request]

A release lever fixed to the fulcrum shaft of the change lever, and a movable release cam that is rotatably and slidably supported concentrically with a release shaft that is engaged with a pin at the tip of the release lever and supported by a clutch cover. , a clutch device disconnection pusher operated by sliding of the movable release cam, a fixed release cam fixed to the release shaft opposite to the movable release cam, and between the fixed release cam and the movable release cam. In a clutch release mechanism consisting of a clamped bearing ball and a pin engaged with the stationary release cam and supported by a clutch cover, a clutch device disconnection pusher, which is operated by sliding of the movable release cam, is located between the outer periphery and the clutch release mechanism. It has a cylindrical shape with a flange at the rear of the inner periphery, and the outer periphery of the front part is fitted to the operating plate via a bearing, and the tip of the release shaft is inserted inside. A clutch release mechanism characterized in that a spring is stretched between the flange and the flange, a cylindrical part of a fixed release cam is fitted on the inner periphery of the rear part, and a movable release cam is brought into contact with the rear end surface.
