<P>PROBLEM TO BE SOLVED: To provide a transmission synchronizing device into which a proper amount of lubricating oil is supplied. <P>SOLUTION: The transmission synchronizing device comprises a synchronizer hub 12 integrated with a main shaft 22 as a rotating shaft, a synchronizer sleeve 14 slidably fitted to the outer periphery of the synchronizer hub 12, and a synchronizer ring 18 to be pushed against the friction face of a synchronizer cone 20 as a synchronized side rotating member along with the axial displacement of the synchronizer sleeve 14. The synchronizer hub 12 has at least one oil path 12A for introducing lubricating oil supplied from an oil pump to the inner periphery, into the outer periphery. When its rotating speed is a predetermined value or higher, an oil path closing mechanism 26 incorporated therein closes the oil path 12A. <P>COPYRIGHT: (C)2009,JPO&INPIT |
