Abstract
A vehicle seat frame includes a pair of side frames constituting side portions of a seat cushion frame, and a pipe member rotatably fitted at respective end portions in sliding holes of the side frames, thereby coupling the side frames to each other. At least one of the end portions of the pipe member is coupled to the corresponding side frame via a collar member having a cylindrical shape. An outer peripheral portion of the collar member has a sliding contact portion in sliding contact with a peripheral surface of the sliding hole. An inner peripheral portion of the collar member has an insertion-receiving portion into which the corresponding end portion of the pipe member is inserted and to which the corresponding end portion of the pipe member is secured. The dimensional tolerance of the sliding contact portion is set smaller than the dimensional tolerance of the insertion-receiving portion.
