Abstract: A vehicle seat can include a stopper capable of stopping a forward tilting of a seat back at a forwardly tilted position, and a stopper operation mechanism. The stopper operation mechanism has a main pivoting member that is pivoted through an operation of a forward tilting operation lever, a sub pivoting member that is pivoted with respect to the main pivoting member, and a connection spring connecting these tilting members to each other. When the forward tilting operation lever is operated, the sub pivoting member receives a force from the connection spring to be pivoted together with the main pivoting member, causing the stopper to move to an acting position. When the stopper is pushed from the acting position toward a non-acting position, with the forward tilting operation lever being operated, the sub pivoting member receives a force from the stopper to elastically deform the connection spring, and is pivoted with respect to the main pivoting member together with the stopper.
