。　−7 A seat bracket attached to the side of the seat;
An intermediate member having one end pivotally connected to the seat bracket and the other end pivotally connected to the back support bracket is provided between the back support bracket attached to the back support side part, and an intermediate member having one end pivotally connected to the seat bracket side. A connecting member is interposed, which is pivotally connected to the seat bracket so as to be at a higher position than the rest of the body, and whose other end is a retaining part that can be engaged with and detached from the engagement pin of the back support bracket. A reclining device in which one link is detachable so that the backrest can be folded forward and folded forward with respect to the seat, and can be tilted back to be fully flat, and the connecting member includes an engaging portion biased toward the retaining pin side. When the intermediate member is tilted forward from a predetermined normal position due to the movement of the backrest and the intermediate member, the intermediate member is tilted forward from the predetermined normal position through the guide surface of the predetermined curved portion and the positioning pin. 1. A seat reclining device characterized by being provided with a lock release means for aligning the engaging portion with the engaging pin and positioning the connecting member at a predetermined position by guiding the rotation of the connecting member using a bracket. −
