が嵩むことになるという不都合がある。(Problem B to be solved by the invention) However, in the case where the synchronized gear constituting the synchronized mesh mechanism is manufactured as a split gear as described above, it includes a gear spline part and a cone part. The annular member forming part is generally completed by forging and then finishing by machining, but the shape of the annular member forming part, which is formed by integrating the gear spline part and the cone part, is The shape is complex to form and machine finish, and its fabrication therefore requires a relatively large number of steps, although not as many steps as if the entire synchronized gear were integrally formed. There are disadvantages in that it does not contribute to steaming, and the material yield deteriorates, leading to an increase in manufacturing costs.
