The second board is mounted to the first board to cover a surface of the first board on an interior side of the vehicle and to be movable along the surface of the first board. The position adjustment mechanism includes an operating component mounted to the second board. The operating component is configured to transmit a force applied to the operating component to the first board to move the second board relative to the first board along the surface of the first board.
