Abstract: A reclining device for a vehicle includes a lower arm secured to a seat cushion of a vehicle seat, and an upper arm secured to a seat back of the vehicle seat. A ratchet plate of which an upper end is secured to the upper arm is turnably supported by the lower arm, and a base end of a pole is also turnably supported by the lower arm. A toothed edge of a lower periphery of the ratchet plate and a toothed edge of a free end of the pole are engaged and disengaged by turning the pole with a release lever. A set plate is disposed so as to face the lower arm through the ratchet plate and the pole. The set plate is supported with two shafts which respectively support the ratchet plate and the pole.
