An intermediate support body (9) is fitted to the top end of the leg column (1), the seat (3) and a back frame (5) are fitted to the intermediate support body (9), and the back support (4) is fitted to the top end of the back frame (5) through a joint device (11). The seat (3) is formed in a rectangular shape in plan view, and horizontally swingably mounted on the intermediate support body (9). The back support (4) can be freely rotated about a first axis (13), and freely swung about a second axis (12).
