いる。In the reclining device according to the present invention, the backlash preventing mechanism includes a second eccentric cam disposed in the inner hole of the eccentric cam, an outer peripheral cam portion of the second eccentric cam, and an inner eccentric cam. A wedge member disposed between the peripheral cam portions, and a spring member for causing the wedge member to bite between the cam portions of the eccentric cam and the second eccentric cam, and the wedge member is eccentric due to the urging force of the spring member. By the biting action between the cam and the cam portion of the second eccentric cam, the external tooth member is pushed integrally to each internal tooth member side via the eccentric cam, and a part of the external tooth of the external tooth member Are reliably engaged with a part of the internal teeth of both internal tooth members.

組付工数の少なくてよい。[0010] The play prevention mechanism that functions as described above is as follows.
The second eccentric cam, the wedge member, and the spring member can be formed into a simple and compact structure, and the backlash prevention mechanism itself is inexpensive. It may be less.

組付性を向上させることができる。The backlash preventing mechanism integrally pushes the external tooth member toward each of the internal tooth members so that a part of the external teeth of the external tooth member becomes a part of the internal teeth of both internal tooth members. Since the reclining device only needs to be provided with one backlash prevention mechanism in order to function so as to engage, a relatively large installation space in the limited mechanism of the reclining device can be ensured. It is not necessary to make each component of the occurrence prevention mechanism so small, and the moldability of each component, and
The assemblability can be improved.

もに、装置に対する組付性を向上させることができる。In the reclining device according to the present invention, the wedge member constituting the backlash prevention mechanism may be configured such that a part of the inner hole diameter of the eccentric cam is larger than that of the general portion,
And a relatively large wedge member can be employed as the wedge member. For this reason, the productivity of the wedge member can be improved as compared with the case of manufacturing a small wedge member, and the assemblability to the device can be improved.

8a rotates to rotate the second eccentric cam 16 and the first eccentric cam 15 so that the external tooth member 13 is rotated while being engaged with the internal tooth members 11 and 12. As a result, the external teeth member 13 becomes the internal teeth 11 of the internal teeth members 11 and 12.
The upper internal tooth member 12 is rotated by rolling on the upper and lower internal gear members 12 and 12b due to the difference in the number of teeth between the two internal tooth members 11 and 12. For this reason, the upper arm 23 and the seat back 24 are tilted in the front-rear direction with the rotation of the upper-side internal tooth member 12, and the tilt angle of the seat back 24 in the front-rear direction is adjusted steplessly. When the rotation of the operation handle 18b is stopped at this time, the rotation of the upper-side internal gear member 12 is stopped, and the seat back 24 is maintained at the adjusted inclination angle.

発生の防止が図られている。In the reclining device 10, the pair of wedge members 17a and 17b and the spring member 17 are provided.
A rattling prevention mechanism having a c is disposed between the first eccentric cam 15 and the second eccentric cam 16. In the hand mechanism for preventing backlash, the wedge members 17a and 17b are formed by the biasing force of the spring member 17c so that the large-diameter arc portion 15c3 of the first eccentric cam 15 and the second eccentric cam 16 forming the housing space 15d. The first eccentric cam 15 is pushed to one side in the radial direction by this biting action, and the external tooth member 13 is pushed into the inner tooth members 11 and 12 by the biting action. Tooth 11
b and 12b are surely engaged with each other. This prevents play between the internal gear members 11 and 12 and the external gear member 13. That is, in the reclining device 10, by the action of the backlash prevention mechanism,
The play between the internal tooth members 11 and 12 and the external tooth member 13 is prevented, and the play of the seat back 24 is prevented.

The space 15d of the two wedge members 17a, 17b is made larger by making the large-diameter arc portion 15c3 of the inner hole 15c of the first eccentric cam 15 larger than the medium-diameter arc portion 15c2, so that the space between the first eccentric cam 15 and the second eccentric cam 16 is increased. To form a large space. For this reason, as the two wedge members 17a and 17b,
It is possible to adopt a large-sized member corresponding to d, so that the productivity of the two wedge members 17a and 17b can be improved, and the assemblability to the device can be improved.
