載のシンクロ機構。[Claims for Utility Model Registration] (1) In a synchro mechanism provided in a transmission, a synchro sleeve that moves in the axial direction, a clutch gear that can be engaged with the synchro sleeve, and an intervening device between the synchro sleeve and the clutch gear. A synchro ring is provided to synchronize the rotations of the synchro sleeve when the synchro sleeve moves to the clutch gear, and a sleeve chamfer is formed at the tip of the teeth of the synchro sleeve, and a synchro ring is provided at the tip of the teeth of the clutch gear. A clutch gear chamfer and a ring chamfer capable of coming into contact with the sleeve chamfer are respectively formed at the tips of the teeth of the synchro ring, and the ring chamfer is composed of a shift up side chamfer and a shift down side chamfer, characterized in that when the sleeve channel contacts the ring channel, the contact area with the shift up side channel is smaller than the contact area with the shift down side channel; synchronized mechanism. (2) Since the above-mentioned ring channel is composed of a shift-up side channel with a small area and a shift-down side channel with a large area, when the sleeve channel comes into contact with the ring channel, the shift-up side channel 2. The synchronizer mechanism according to claim 1, wherein the contact area with the shift-down side chamfer is set to be smaller than the contact area with the shift-down side chamfer. (3) The neutral position of the ring chamfer in the rotational direction with respect to the sleeve chamfer is biased, so that when the sleeve chamfer abuts the ring chamfer, it comes into contact with the shift-up side chamfer. 2. The synchronizing mechanism according to claim 1, wherein the area is set to be smaller than the area of contact with the shift down side channel.
