Claims

[Scope of utility model registration request]

The shift mechanism 11 includes a shift mechanism 11 that mutually connects and disconnects a PTO main shaft 6 that is connectably connected to the engine via a clutch and a PTO transmission shaft 8 that is supported coaxially with the PTO main shaft 6. In a tractor that can be switched between ground PTO and live PTO by a switching operation, male splines 18 and 19 are provided at each mutually opposing end of the PTO main shaft 6 and PTO transmission shaft 8. The mechanism 11 includes a shift body 17 that is spline-fitted to one shaft end so as to be freely operable in the axial direction, and a shift body 17 that is spline-fitted to the other shaft end in a manner that prevents the mechanism from coming off, and that provides a buffer in the direction of the one shaft end. The connecting body 16 is elastically biased by a spring 20, and can be freely engaged and disengaged by the axial direction operation of the shift body 17 to each opposing transmission surface 25, 26 of the shift body 17 and the connecting body 16, which face each other. Transmission pawl 2 that engages with and rotates in the same direction.
7 and a driven pawl 28, respectively, and a cylindrical support protrusion 29 on which the shift body 17 is removably fitted and supported is protruded from the other shaft end. Grand Live PTO switching device.
