Claims

[Claims for Utility Model Registration] (1) A gear that is loosely fitted onto an input shaft and meshes with a gear on an output shaft, a clutch hub that is fixed to the input shaft, and a gear that is integrally fitted with the loosely fitted gear. a gear spline provided; a hub sleeve that spline-engages with the clutch hub, rotates integrally with the hub, and slides on the outer periphery of the clutch hub in the hub axial direction to selectively engage the gear spline; A cone part integrally formed with the loosely fitted gear, and a cone part arranged outside the cone part so as to be rotatable relative to the cone part, and spline engaged with the hub sleeve when the hub sleeve slides. A gear having a synchronizer ring, and a synchronizer key that is held by the clutch hub and engaged with the synchronizer ring, moves as the hub sleeve slides, pushes the ring, and frictionally engages the cone portion. In the transmission, a recess is formed on the outer peripheral surface of the synchronizer ring opposite to the inner peripheral surface of the cylindrical portion formed at the outer peripheral end of the clutch hub, and the cylindrical portion is disposed within the recess at least when the ring rotates. A gear transmission characterized by being provided with a contact member that presses against an inner circumferential surface of the gear transmission. (2) The abutment member is supported within the recess so as to be freely movable in the radial direction of the synchronizer ring, and is pressed against the inner circumferential surface of the cylindrical portion by centrifugal force when the ring rotates. A gear transmission according to claim 1 of the utility model registration claim, characterized in that: (3) The utility model according to claim 1, characterized in that the abutting member is urged by an urging means so as to be in constant pressure contact with the inner peripheral surface of the cylindrical portion. Gear transmission.
