A vehicle transmission includes a shaft; speed-changing gears; switching mechanisms; and a shifting mechanism. The shifting mechanism is provided with a double-meshing preventing mechanism configured to switch between a one-way state in which the switching mechanisms are hindered from moving in a downshift direction and allowed to move in an upshift direction and a free state in which the switching mechanisms are allowed to move in both the downshift direction and the upshift direction.

A ball joint generates play when wear of a ball sheet reaches a predetermined allowable amount so that the end of service life of the ball joint can be recognized by a simple inspection. A spherical portion of a ball stud is interposed between an upper sheet and a lower sheet. The upper sheet is displaced toward the lower sheet when the upper sheet or the lower sheet has been worn due to sliding of the spherical portion. The displacement of the upper sheet is restricted so that the upper sheet is supported at a predetermined position relative to the lower sheet.
