Patent ID: 8297704

Claim:
A connector for a vehicle seat used to connect a first connected member and a second connected member to each other in such a manner that the first connected member and the second connected member are pivotable with respect to each other, comprising: a first connection disc member and a second connection disc member that are connected integrally with the first connected member and the second connected member, respectively, and that are coaxially fitted together in such a manner that the first connection disc member and the second connection disc member are rotatable with respect to each other; and at least one lock member that is arranged between the first connection disc member and the second connection disc member, that is fitted to the first connection disc member and supported so as to be movable in a radial direction of the first connection disc member, and that is moved outward in the radial direction so that an outer peripheral toothed face of the at least one lock member meshes with an inner peripheral toothed face of the second connection disc member, thereby preventing relative rotation between the first connection disc member and the second connection disc member, wherein the second connection disc member has a disc portion and an annular wall that is formed on an outer periphery of the disc portion, that extends in an axial direction of the second connection disc member, and that has an inner peripheral face in which the inner peripheral toothed face is formed, the first connection disc member has multiple annular-wall support portions that project from an inner disc face of the first connection disc member, which faces the second connection disc member, in an axial direction of the first connection disc member, the first connection disc member has a recess that projects from the inner disc face in a direction opposite the axial projecting direction of the multiple annular-wall support portions, the recess being configured to accommodate the at least one lock member, and the inner peripheral face of the annular wall of the second connection disc member is in contact with and supported by the annular-wall support portions.
