PURPOSE:To make a fixed section or a rotary section easily retain a sealing unit while the sealing property between them is assured, and to eliminate the possibility of sealing failures caused by improper adhesive application, pin holes and an uncured adhesive. CONSTITUTION:A first annular groove 50 is formed along the inner circumferential surface of a sealing section 26d. A resilient annular body 52 is fitted into the first annular groove 50 over the entire circumference thereof while it is vertically compressed, so that the annular body is held by the groove. An inner projecting portion 52a of the resilient annular body 52 is fitted into a second annular groove 62 of a sealing unit 54. While the inner projecting portion 52a is vertically pressed over the entire circumference thereof, the sealing unit 52 is retained by a sealing section 26d. |
