え、全体の構造が複雑になる不都合があつた。 Conventionally, in the shaft drive transmission system of a motorcycle, a drive bevel gear is interlocked with a countershaft of a transmission gear mechanism in a transmission case, and a driven bevel gear provided on a final shaft that is interlocked with a rear wheel is meshed with this bevel gear. There is a known system in which the rotation of the countershaft is transmitted to the final shaft.However, in such a system, it is difficult to perform maintenance on the interlocking connection between the countershaft and the final shaft. Not only does this require a large opening for the shaft case, which impairs work efficiency, but it also requires a special bearing for the drive bevel gear connected to the countershaft, increasing the number of parts and complicating the overall structure.
