ング装置。 A planetary gear is provided between the lower arm fixed to the seat cushion side and the upper arm attached to the rear part of the lower arm so as to be able to rotate by a predetermined amount in the longitudinal direction and fixed to the seat back side, for finely adjusting the inclination angle of the upper arm in the longitudinal direction. A seat reclining device comprising a unit type fine adjustment mechanism and a ratchet pole type coarse adjustment mechanism for coarse adjustment, and a restriction means for restricting the adjustment range by the fine adjustment mechanism. A first rotating body is provided rotatably on the rotating shaft of the adjustment mechanism, and a second rotating body is rotatably provided on the lower arm side and partially overlaps with the first rotating body. The first rotating body is provided with an engaging pin protruding from a portion deviated from its center of rotation, and the second rotating body is provided with an engagement pin on its outer periphery at a predetermined distance in the rotational direction. a pair of engagement recesses with which the engagement pin selectively engages to restrict the rotation of the rotation body when the rotation body rotates in forward and reverse directions; A reclining device for a seat, characterized in that a plurality of elongated holes are provided at equal intervals on the outer periphery, and the engaging pin advances and retreats when the first rotating body rotates, thereby rotating the second rotating body.
