うな形状に設定したことを特徴とする異音防止装置。A gear shift system in which a synchronized mesh device is installed on the axis of a shaft that rotates in response to torque transmission from the prime mover in a neutral state, providing drag resistance to the rotation of the shaft through synchronization during the initial stage of the shift operation. In the machine, a shift fork that provides a shift operation force to this synchronized mesh device is attached so that it can slide relative to the fork shaft, and on the axis of this fork shaft, it is attached to A stopper that moves to shift the shift fork is fixed, and a spring made of shape memory alloy is installed between this stopper and the shift fork. When the temperature inside the transmission exceeds a certain value, this spring expands and shifts the shift fork. An abnormal noise prevention device, characterized in that it is set in a shape that causes the synchromesh device to cause a synchronizing action by moving in a shift direction along a fork shaft.
