合不良を来たし、歯飛現象が生ずる。(Problem to be Solved by the Invention) Among the above-mentioned known publications, the one in Japanese Utility Model Publication No. 55-54367 discloses that the inner edge g of the claw portion d of the ratchet c has a small radius r, and the outer edge h has a large radius R. Since the outer edge h moves more because of the difference in radius, the outer edge h moves more. Therefore, when the claw d of the latch c faces the outside of the recess b of the latch a, there is a large gap between the tip i of the outer edge h and the latch a, as shown in Fig. 2.
A gap is formed and it becomes lifted. When a gap is formed in this manner, a positional shift occurs, and the tip i of the claw portion d rides on the corner of the recessed portion b, resulting in poor engagement and a tooth-skipping phenomenon.

る。 Next, the latch described in Japanese Utility Model Publication No. 55-54365 has an elliptical outer peripheral edge, and a part of the elliptical outer peripheral edge is cut out to form a rectangular recess with a notched edge on one side. The tip edge of the pawl of the ratchet that engages with the L-shaped recess is formed into an arcuate surface that can be brought into close contact with the groove bottom of the L-shaped recess over the entire width,
Since the tip edge of the claw portion of the ratchet does not have a shape that closely contacts the outer circumferential arc surface of the latch, which is a perfect circle, over the entire width, when the claw portion faces the rectangular recess, the state shown in FIG. 2 is obtained.

出部は非常に高いものになり、危険である。 Furthermore, in the conventionally known device described in JP-A No. 56-80214, a bulge is formed on the outer surface of the toothless portion on the side far from the axis of the recess, so the pawl of the ratchet is bulged. Although it is possible to prevent tooth skipping due to hitting the part,
The tip edge of the claw of the ratchet that engages with the recess is shaped to match the bottom groove of the recess, so the tip edge of the claw of the ratchet will be in the state shown in Figure 2, so the bulge will be very high. and is dangerous.

に高いものになり、危険である。(Effects) Among the above-mentioned known publications, the one disclosed in Japanese Utility Model Publication No. 55-54367 is that the inner edge g of the claw portion d of the ratchet c moves with a small radius r, and the outer edge h moves with a large radius R. Due to the difference in radius, the outer edge h moves more. Therefore, when the pawl d of the latch c faces immediately outside the recess b of the latch a, there is a large gap between the tip i of the outer edge h and the latch a, as shown in Fig. 2.
A gap is formed and it becomes lifted. When a gap is formed in this way, a positional shift occurs, and the tip i of the claw portion d rides on the corner of the recessed portion b, resulting in poor engagement and a tooth-skipping phenomenon. Furthermore, in the latch described in Japanese Utility Model Publication No. 55-54365, the outer peripheral edge of the latch is elliptical, and a part of the elliptical outer peripheral edge is cut out to form a rectangular recess with a notched edge on one side. The tip edge of the claw of the ratchet that engages with the mold recess is formed into an arcuate surface that can be brought into close contact with the groove bottom of the R-shaped recess over the entire width; Since the shape of the latch is not in close contact with the circular arc surface of the circular latch, when the claw portion faces the rectangular recess, it will be in the state shown in FIG. 2 above. Furthermore, in the conventionally known device described in JP-A No. 56-80214, a bulge is formed on the outer surface of the toothless portion on the side far from the axis of the recess, so the pawl of the ratchet is bulged. However, since the tip edge of the ratchet claw that engages with the recess is shaped to fit the bottom groove of the recess, the tip edge of the ratchet claw will be in the state shown in Figure 2. Therefore, the bulge becomes very high and dangerous.

The latch 4 is fixed, and a latch 6 that engages with the latch 4 is fixed on the other side by a shaft 7,
The outer peripheral edge of the latch 4 is an arc-shaped toothless portion 12 having the same radius centered on the shaft 13, and the toothless portion 12
A U-shaped recess 3 having notched edges on both sides is formed by cutting out a part of the toothless part 12, and the recess 3
The tip edge 1 of the pawl portion 5 of the ratchet 6 that engages with the
1 is formed into an arcuate surface that can be brought into close contact with the toothless portion 12 of the latch 4 over the entire width, and a protruding portion 14 for preventing tooth skipping is provided on the outer surface of the toothless portion 12 on the side farther from the axis 7 of the recess 3. Since it is used as a reclining device for a vehicle seat, the tip edge 11 of the claw portion 5 is formed into an arc that closely fits the perfect circle outer periphery of the latch 4 over the entire width. Even when it slides on the toothless part 12 and faces the upper part of the recessed part 3, it faces the recessed part 3 immediately, so that it easily and reliably engages with the recessed part 3.
