Half Locking) can be completely eliminated.

For example, when the operating lever 30 is rotated for seat back tilting or folding, as shown in FIG. 1, the first end of the pressing end 31 of the operating lever 30 is positioned in the rotation path. The lock state is released by applying a force to the 2, 3, 4, 5 restraints 11, 12, 13, 14, and 15.

This is because the respective roller pins 20a constituting the first, second, third, fourth, and fifth restraints 11, 12, 13, 14, and 15 are forced by the rotation of the operation lever 30, and this force Through the roller pin 20a is achieved by overcoming the repulsion of the spring that is the joining member (20b).

When the operation lever 30 is returned after such an operation, each roller pin 20a constituting the first, second, third, fourth, and fifth restraints 11, 12, 13, 14, and 15 is joined to the joining member 20b. Under the force of the in-spring, it is sandwiched between the teeth forming the gear stage 5 of the feed plate 3 and switched to a contacted state to form a locked state, and at the same time the teeth of the gear stage 5 It is to implement a zero chuck state that the play is blocked.

Such an operating state is shown in FIG. 2, for example, in the case of a 12.6 ° incline, each roller pin constituting the first, second, third, fourth and fifth restraints 11, 12, 13, 14, and 15. Two roller pins in the 20a form a state in contact with the gear stage 5 of the retaining plate 3.

That is, one of the two roller pins forms a contact Ka with respect to the teeth of the gear stage 5, and the other one roller pin also forms a contact Kb with respect to the teeth of the neighboring gear stage 5. .

At this time, the two roller pins are inserted into the teeth of the gear stage 5 and do not implement the engaged state, but the two roller pins are in contact with the teeth of the gear stage 5, so that the contact Ka, Kb state is formed, so that locking ( At the same time, a zero chuck state is formed in which the play is blocked due to the contact Ka and Kb states.

The same is true for a -7.6 ° slope.

In the case of the 11.6 ° inclined state, two roller pins among the roller pins 20a constituting the first, second, third, fourth, and fifth restraints 11, 12, 13, 14, and 15 are gear ends. The contact Ka and Kb states are formed in the teeth of (5), and one roller pin is formed in the bite L state in which the roller pins are sandwiched between the teeth of the gear stage 5.

In this state, the impact strength is improved by forming a strong restraint state through the bite L state of the gear stage 5 of one roller pin, and the gear stage 5 in the contact Ka and Kb states of the two roller pins. A zero chuck state is created that blocks the play of the play.

Thus, when two roller pins form the contact Ka and Kb states with the teeth of the gear stage 5 simultaneously with the bite L state in which one roller pin is sandwiched between the teeth of the gear stage 5, it is 10.6. The same is true for the °, 9.6 °, -8.6 °, -6.6 °, and -5.6 ° slope conditions.
