PROBLEM TO BE SOLVED: To enable easy and inexpensive manufacture by receiving pins in holes extended in the diametral direction of a shaft, and using a shift key, a key groove or an interlock key, shift yoke hubs or housings for replacing one of both of the key grooves. SOLUTION: Provided are a shifting shaft, a yoke assembly 300 (a shifting shaft assembly), and shift yoke hubs 302, 304, 306. The shifting shaft assembly has a shaft 308 having a key groove 310 for receiving an interlock key 312 samely formed as the interlock key 312 in its structure and mechanism. A shift block member 314 is fixed to the shaft 308. In the shaft assembly, sift pins 316, 318, 320 are extended from the shaft 308 in a diameter direction and fixed thereto for providing selection mechanism, and pushed into blind holes 322, 324, 326 the surface of the shaft 308 in the diameter extended on the surface of the shaft 308 in the diameter direction. A uniaxial shift mechanism is economically manufactured and assembled by the use of pins for replacing the key and key groove. |
