Claims

[Scope of utility model registration request]

A first gear and a second gear having the same diameter are coaxially rotatable independently of each other, and a third gear is thrust-moved relative to both of the gears to rotate between the first and second gears. In the gear switching mechanism formed by selectively meshing, the third
A gear switching mechanism characterized by widening the thrust width of some of the teeth of the gear.
