Claims

[Claims for Utility Model Registration] 1. Between a sleeve disposed on the spline on the outer periphery of the clutch hub and operated to shift in the axial direction, and a clutch gear disposed on the same axis to mesh with the operated sleeve, A synchronizer is equipped with a blocking ring to synchronize the rotational speeds of both clutch hubs and sleeves, and the end of the key installed between the clutch hub and sleeve is inserted into a keyway formed in the blocking ring that is wider than the width of the key. In the nizer, a spring piece that engages the clutch hub and the block ring and exerts an elastic force on the block ring in the circumferential direction so that the key is located in the center of the width of the keyway is attached to a spring piece that is separate from the key and the keyway. A synchronizer characterized by being attached to a certain point. 2. The synchronizer according to claim 1, further comprising a coil spring that draws the blocking ring toward the clutch hub in the axial direction, and is installed at the same location as the spring piece.
