Claims

[Scope of utility model registration request]

a clutch hub connected to the rotating shaft of the transmission;
A sleeve attached to the outer periphery of the clutch hub so as to be movable in the thrust direction, a reverse gear disposed in the direction of movement of this sleeve, and the clutch hub are arranged to be movable slightly in the thrust direction and movable in the radial direction. a block member disposed in such a manner that the sleeve can be moved; a convex portion extending outward from the inner circumferential end of the sleeve and against which the sleeve comes into contact when the sleeve is moved is formed on the block member; The sleeve abutting surface is inclined obliquely outward, and by moving the sleeve, the blocking member is moved inward toward the reverse gear, and as a result, the blocking member is moved toward the reverse gear. In a power transmission device configured to abut against an end face in a thrust direction of a reverse gear, the surface that the block member of the reverse gear abuts is inclined diagonally outward, and the reverse gear of the block member A power transmission device characterized in that a surface that comes into contact is inclined diagonally inward corresponding to the inclined surface of the reverse gear.
