VEHICLE SEAT

A vehicle seat includes a base part, a first movable part, a second movable part, a lock member, and an interlocking mechanism configured to link movement of the lock member to movement of the second movable part. The interlocking mechanism includes an attaching member, a first rotational member connected to the second movable part, a second rotational member connected to the lock member, and a swingable member provided swingably on the second rotational member. The engagement of the swingable member and the first rotational member causes the first rotational member and the second rotational member to rotate together, whereby the lock member moves from a lock position to an unlock position. The swingable member disengaging from the first rotational member permits the first rotational member and the second rotational member to rotate independently, whereby the lock member moves from the unlock position to the lock position.
