機におけるシンクロメツシュ機構。A shifting key fitted in a key groove on the outer periphery of the clutch hub is pressed by a key spring against an internal spline of a hub sleeve fitted with a spline on the outer periphery of the clutch hub, and is pressed against one side of the hub sleeve and the shifting key. A synchronizer ring and a forward gear are provided, and the hub sleeve moves toward the synchronizer ring during a forward shift, and moves toward the side where the synchronizer ring is not provided during a reverse shift. A holding mechanism is disposed on the other side of the shifting key to hold the shifting key in a neutral position during a predetermined shift in which the hub sleeve moves in one direction. A synchromesh mechanism for a transmission, characterized in that retaining portions are formed on the surface facing the key to engage with each other during the predetermined shift to prevent the hub sleeve from moving in the return direction.
