Abstract
A shifting mechanism, in which a movable member integrated with an engagement pin will not be rotated by a friction acting between a cam groove and the engagement pin, includes: a shift drum that on which a cam groove is formed; a cam sleeve having an engagement pin inserted into the cam groove; a fork shaft reciprocated between predetermined positions by rotating the shift drum; a support stem extending parallel to a center axis of the cam sleeve; and a projection formed integrally with the cam sleeve to come into contact with the support stem when the cam sleeve is rotated.
Claims2
A shifting mechanism, comprising:
- a shift drum on which a cam groove is formed;
- a cam sleeve having an engagement pin that is inserted into the cam groove to be reciprocated by the cam groove;
- a fork shaft that is reciprocated between predetermined positions by a thrust force of the cam sleeve established by rotating the shift drum;
- a support stem that extends parallel to a center axis of the cam sleeve;
- and
- a projection that is formed integrally with the cam sleeve,
- wherein the projection comprises a through hole to which the support stem is inserted,
- wherein the through hole includes a slotted hole having a length in a direction along a normal line of the cam sleeve longer than a width thereof, and
- wherein a rotation of the cam sleeve is restricted when the support stem comes into contact to an inner wall surface of the slotted hole.
