速機のシフト機構。[Claims for Utility Model Registration] (1) A neutral position where each gear train can be selected; a first select position that is arranged apart from the neutral position and can achieve any of the gear trains; A vehicular transmission comprising a shift piece movable at least between a first select position and a second select position which is disposed on the side farther from the first select position in the same direction and can achieve a different gear train. In the shift mechanism, a first elastic member interposed between the neutral position and the first select position and biasing the shift piece toward the neutral position with a first elastic force; and the first and second select positions. A second elastic member interposed therebetween and urging the shift piece in the direction of the first select position with a second elastic force greater than the first elastic force. Machine shift mechanism. (2) The shift mechanism includes a shift select shaft that moves in the axial direction together with the shift piece, and a sliding receiving part that is arranged to be slidable on the shift selecting shaft, and the sliding The receiving part is biased between the stationary part via the first elastic member on one side and the shift piece via the second elastic member on the other side. 2. The shift mechanism for a vehicle transmission according to claim 1.
