Claims

[Scope of utility model registration request]

The key type synchronous transmission includes a main shaft, a synchronizer hub fixed to the main shaft, a sleeve fitted to the outer periphery of the synchronizer hub so as to be movable in the axial direction of the main shaft, A plurality of grooves parallel to the axial direction of the main shaft are formed on the outer peripheral surface of the hub, and a projection is movably inserted into each of the grooves and can be engaged with a recess formed on the inner wall surface of the sleeve. a plurality of synchronizer keys, a synchronizer ring provided with notches into which the end faces of the synchronizer keys can be respectively fitted, and a cone portion that can make contact with a tapered portion formed on the inner surface of the synchronizer ring. The plurality of synchronizer keys are divided into a plurality of groups, and the timing at which the protrusion of each synchronizer key in each group engages with the recess is different from that of the protrusion of each synchronizer key in other groups. A synchronous mesh transmission for an automobile, characterized in that the timing of engagement of the recess is shifted from the timing of engagement of the recess.
