機の異音防止装置。 A shaft that rotates when it receives rotation from the engine when it is idling, and a shaft that does not rotate when it is idling, are arranged parallel to each other in the transmission case, and a synchronizer is installed on the axis of the shaft that does not rotate when it is idling. In gear transmissions equipped with a locking mechanism,
The outer periphery of the hub sleeve of the synchronized mesh mechanism, which is in the neutral state, is placed on the shaft of the shaft rotating in the idling state due to the action of a shape memory alloy spring that deforms when the oil temperature in the transmission case exceeds a certain value. A noise prevention device for a gear transmission, characterized by assembling a friction contact member that is pressed against the gear transmission.
