Abstract:
1. A connecting apparatus for rotatably connecting two object members of a vehicular seat relative to each other comprising: first and second connecting members integrated to be able to rotate relative to each other, the first connecting member integrally connected to one of the two object members, the second connecting member integrally connected to the other one of the two object members; a lock member arranged between the connecting members and integrated to the first connecting member to be supported in a circumferential direction, the lock member being able to lock the relative rotation between the connecting members when outer peripheral teeth mesh with inner peripheral teeth formed at the second connecting member; and an operating member moving the lock member between a mesh state and a release state, in the mesh state the outer peripheral teeth of the lock member mesh with the inner peripheral teeth of the second connecting member, in the release state the outer peripheral teeth are released from the inner peripheral teeth; wherein the second connecting member is formed with a circular cylinder portion and a support portion each respectively having a circular cylinder shape, the circular cylinder portion being formed with the inner peripheral teeth at an inner peripheral face thereof, the support portion being arranged at an outer side in a radius direction relative to the circular cylinder portion and projects from the circular cylinder portion in an axial direction towards the first connecting member, the support portion receiving a circular ring portion formed at the first connecting member to surround the circular ring portion from an outer peripheral side to support each other to be able to rotate relative to each other, and the circular ring portion of the first connecting member is spaced from the outer peripheral teeth of the lock member in both the release state and the mesh state.
