Abstract

A reclining apparatus achieves enhanced ease of coming off of a pole from a ratchet plate and hence a better operational feeling. Of a plurality of external teeth of a pole, at least one external tooth from an end is formed in such a manner that a tooth thickness is lessened more toward a tooth tip in comparison with a tooth thickness of other external teeth. The external tooth having a lessened tooth thickness is cut in one of two tooth planes located on a side of the end. The cut tooth plane has an inclined surface parallel to a flat surface containing all tangential lines to a pitch circle of one of two tooth planes of an external tooth having a large tooth thickness and situated adjacent to the external tooth having a lessened tooth thickness located on a side of the external tooth having a lessened tooth thickness.

Description

technical field [0001] The present invention relates to a backrest reclining device which is in a locked state by meshing of inner teeth and outer teeth. Background technique [0002] 11 and FIG. 12 are used for description. FIG. 11 is a configuration diagram of a seat, and FIG. 12 is a side view of a conventional backrest reclining device for a vehicle seat. [0003] As shown in FIG. 11 , the seat 101 includes a seat cushion 102 that supports the buttocks of the seated person and a seat back 103 that supports the back of the seated person. The seat back 103 is tiltably provided in the front-rear direction of the seat cushion 102 . The backrest reclining mechanism 104 is provided on the rotation axis of the tilting of the seat back 103 , and allows / prohibits the tilting of the seat back 103 . [0004] The backrest reclining device 104 will be described using FIG. 12 . In the figure, a hinge pin 131 is erected on the lower arm plate 130 provided on the seat cushion side. ...
