<P>PROBLEM TO BE SOLVED: To provide a synchronous joining mechanism of a transmission capable of effectively reducing friction by a drag of a friction surface of a blocking ring, with a simple constitution of not requiring labor and cost for manufacture. <P>SOLUTION: The blocking ring 20 of this synchronous joining mechanism 10 has a synchronous cone 25 arranged between an outer ring 21 and an inner ring 23. The synchronous cone 25 has an engaging part 30 for allowing tapered friction surfaces 25a and 25b inclining in the axial direction to abut on the outer ring 21 and the inner ring 23, and relatively nonrotatably engaging with a shift gear 3. A coil spring (an elastic member) 32 is interposed between an engaging hole 28 and an engaging projection 29 in the engaging part 30, and the friction surface 25b is energized in the direction for separating from the inner ring 23 by pressing the synchronous cone 25 to the synchronous hub 6 side by this coil spring 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
