SYNCHRONOUS CONNECTING DEVICE FOR TRANSMISSION

PROBLEM TO BE SOLVED: To provide a synchronous connecting device (synchro mechanism) capable of reducing friction in normal driving, and further reducing synchro load (shifting operation load). SOLUTION: In this synchronous connecting device for a transmission comprising a blocking ring composed of an outer ring mounted at a radial outer side, an inner ring mounted at a radial inner side and relatively unrotatably locked on the outer ring, and a synchro cone held between the outer ring and the inner ring, the synchro cone is formed into the circular wave form so that the outer ring and the inner ring are alternately kept into point-contact with each other at a position where the synchro cone is separated at a prescribed angle in the circumferential direction, when a synchro sleeve is kept on a neutral position.
