The present invention relates to a recliner of a vehicle seat, which comprises: an external gear bracket wherein an external gear is formed in an inner side; an internal gear bracket wherein a central protrusion is formed in the center; a socket coupled between the external gear bracket and the internal gear bracket; two wedge blocks rotated by the socket and arranged in different circumferences from each other; a wedge spring wherein both ends are arranged in different circumferences from each other for end portions adjacent to each other in the wedge blocks to be respectively pushed; and a cam sliver wherein a side portion adheres to an outer circumferential surface of one wedge block, and the other side portion adheres to an inner circumferential surface of the other wedge block. Therefore, The wedge blocks rotated by the socket are arranged in different circumferences. The wedge spring elastically pushing the wedge blocks is formed to be spiral. Thus, maximum tension of a spring in accordance with extension increase is reduced. |
