Claims

[Scope of utility model registration request]

A plurality of forks and a plurality of arms each fixed to the inner end of a double operation shaft that is arranged perpendicular to the speed change direction of the forks and can be rotated separately, are arranged in the speed change direction and can slide against each other. A transmission device in which each fork is pivotally connected by a double rod, and each fork is slid individually by selective operation of a speed change lever provided on a double operation shaft protruding from the outside of the case.
