Claims

[Scope of utility model registration request]

A first linked free gear to which power is transmitted from the transmission shaft is loosely fitted to the output shaft, and a first gear shift gear spline-coupled to the output shaft is slid in one direction to engage with the first linked free gear. In a transmission device for a motorcycle in which the first gear is set to the first gear and the other gear is slid to perform other gear shifting operations, and a neutral position is set at an intermediate position, the inner circumferential surface of the first gear shift gear is provided. A plurality of recesses are formed at predetermined intervals along the circumferential direction, and the splines of the output shaft corresponding to the recesses are notched by a predetermined width in the axial direction, and when the output shaft is stopped, a plurality of recesses are formed in the recesses. , is located in the notch of one of the above splines and only allows movement according to the notch width of the spline, and when the output shaft rotates, it comes off from the spline due to centrifugal force and is protected from other transmission gears. 1. A transmission device for a motorcycle, characterized in that a ball is arranged to enable movement of a first speed shift gear necessary when the gear is shifted.
