Then, it is formed so as to be locked and connected to the locking portion 8-22 again. In other words, when the rotation of the output shaft 6-1 is switched from the normal rotation to the reverse rotation, the output transmission arm is started from the time when the connecting boss 8-10 is locked and connected again from the sliding portion 8-21 to the locking portion 8-22. 8-2 is moved forward from the retreat limit to the forward limit (Fig. 5
