FIGS. 1A to 1C are partially enlarged cross-sectional views showing different working states of the present invention, and FIGS.
A diagram showing the state when the ratchet pin 8 jumps up,
Figure 2 shows the ratchet pin 8 being held in the ratchet pin insertion hole 6 and rotating in the normal direction, and Figure 3 shows the ratchet pin 8 being caught in the wall portion 7c of the toothed groove 7, preventing the rotating shaft 1 of the motor from reversing. FIG. 2 is a partially enlarged sectional view showing another embodiment of the present invention in which a pressure balance hole 12 is provided in the ratchet cover 10, and FIGS. Fig. 3A and Fig. 3B are respectively a front view of the ratchet pin 8 held in the ratchet pin insertion hole 6 and rotated in the normal direction, a view along the circumferential direction, and Fig. 4 Figures A and B are a front view and a circumferential view, respectively, of the ratchet pin 8 hooked onto the wall surface 7c of the toothed groove 7 to prevent reverse rotation.

して設けたことを特徴とするラチエツト装置。 A ratchet disk in which a plurality of ratchet pin insertion holes are drilled at regular intervals along the circumferential direction and a ratchet receiver in which tooth-shaped grooves are continuously formed along the circumferential direction are vertically opposed to each other. The ratchet pin is arranged so as to face the ratchet and is inserted into the ratchet pin insertion hole of the ratchet disc so as to be slidable in the vertical direction, and the ratchet pin is engaged with the toothed groove of the ratchet receiver to prevent the ratchet disc from rotating in the opposite direction. A ratchet device characterized in that a small-diameter pressure balance hole is provided to pass through a ratchet cover that closes the upper end of the ratchet pin or the ratchet pin insertion hole.
