Clutch release mechanism.

Abstract

To provide a clutch release mechanism which does not require a large number of components and which can contribute toward a cost reduction. A clutch release mechanism is provided which includes a fixed cam member (46) supported by a support shaft (45), rotation preventing means (53) provided between the fixed cam member (46) and a crankcase (15) to prevent the fixed cam member (46) from rotating about the support shaft (45), and a movable cam member (47) installed, in a position opposing the fixed cam member (46), to be rotatable coaxially with the support shaft (45). The rotation preventing means (53) includes a rotation preventing shaft section (54) which is formed, integrally with an arm (51a) radially outwardly extending from the fixed cam member (46), by bending a portion of the arm (51a) to be parallel with the support shaft (45), and a rotation preventing hole (55a) which is formed on an inner side of the crankcase (15) and into which the rotation preventing shaft section (54) is fitted.
