To satisfactorily hold a plug within a hollow part, the plug being fitted into the hollow part of a counter shaft.
A counter shaft 40 includes a hollow part 400 which extends in an axial direction and has openings 401, 402 at both ends. In one end of the counter shaft 40, a diameter reduced part 403 is formed on which a bearing 45 is mounted by reducing a shaft outer diameter. The hollow part 400 includes a first hollow part 400a which communicates with the opening 401 at one end and has a fixed inner diameter to a step 400s closer to the other end of the counter shaft than the diameter reduced part 403, and a second hollow part 400b which further extends from the step 400s to the other end side of the counter shaft 40. Within the first hollow part 400a, a plug 50 is fitted via the opening 401 so that the entire plug is positioned more on the other end of the counter shaft 40 from the diameter reduced part 403, namely, from an annular surface 404.
