Claims

[Scope of utility model registration request]

A synchronizer hub is fixed to a rotating shaft of a transmission, a synchronizer sleeve is engaged with an outer spline of the synchronizer hub so as to be movable in the axial direction by an inner spline of the sleeve, and a synchronizer key is pressed inside the synchronizer sleeve by a key spring. In the synchronous meshing device for a transmission, the synchronizer ring has a synchronizer ring that is movably engaged in the circumferential direction with a gear outer taper cone portion of the transmission gear by a ring inner taper cone portion, wherein the synchronizer key inner side is pressed by the key spring. A synchronous meshing device for a transmission, characterized in that a notch is provided by cutting out the remaining inner side of the synchronizer key toward the outer side of the synchronizer key.
