Claims

[Claims for Utility Model Registration] (1) An intermediate gear plate having an outer gear;
an upper arm having an inner gear that meshes with the outer gear of the intermediate gear plate; a rotating shaft in which the intermediate gear plate and the upper arm are rotatably attached to concentric and eccentric portions; and a rotating shaft that cooperates with a sub-plate. a lower arm for supporting the lower arm; a release lever for unlocking the intermediate gear plate from the lower arm and performing rapid forwarding; and an operation handle for fine adjustment for rotating the rotary shaft via a chain transmission device. The reclining device is configured to transmit rotation of the operating handle to the rotating shaft via a brake mechanism, and a part of the chain of the chain transmission device is protruded, and the protruding portion is A reclining device characterized in that the reclining device is configured to set a fine adjustment range of the reclining angle by being provided on the lower arm side and brought into contact with a stopper. (2) The reclining device according to claim 1, wherein the cover bracket of the brake mechanism is used as the stopper.
