Abstract: The number of components required to restrict the movement of an operating section, when a cushion frame is moved in the height direction, and a link member, which is for moving the cushion frame, is reduced. The seat is provided with: a drive link that is rotatably attached to the cushion frame and that moves the cushion frame in the height direction according to rotation thereof; a gear part that engages with the drive link and that rotates the drive link; a link-rotation restricting member for restricting the rotation range of the drive link; an operating section that accepts an operation for adjusting the height of the cushion frame; and a rotation application section for rotating the drive link via the gear part according to the operating section. The movement of the operating section is restricted as a result of the link-rotation restricting member abutting against the rotation application section.
