~216c. By the way, each boss portion 211b to 213b, which is a mounting base of each shift fork 211 to 213, is attached to the fork holding shaft 21.
Each shift fork 211-2 on 4,215
13, that is, each shift fork 211-213 needs to be formed long in the axial direction so that it does not tilt during movement and prevent smooth sliding with the fork holding shafts 214, 215. . In addition, in particular, the shift forks 211 and 212 mounted on the fork holding shaft 214 must be arranged with a predetermined interval maintained so that their respective boss portions 211b and 212b do not interfere with each other, and must be arranged in the axial direction of the fork holding shaft 214. This requires a large installation space. As a result, the fork holding shaft 2
14 and the cam cylinder 216 are relatively long, making it difficult to construct this type of variable speed gear shift device compactly.
