Abstract: PURPOSE:To make it possible to prevent fluid from leaking along the spiral direction of a sealing member as much as possible by providing protruded members on the two neighboring surfaces of the sealing member, which opposes to the bottom surface of a groove section and side wall, being misregistrated in the spiral direction. CONSTITUTION:On the two neighboring surfaces of a sealing member 1 opposing to the bottom surface of a groove section 2 and a side wall, protruded members 5a and 5b are provided so as to be elastically pressed to the side of the groove section 2 receiving the pressure applied to the outer area side from the center area side in the spiral direction of the sealing member 1. At this place, the protruded member 5a formed on the side 1a of the bottom surface of the sealing member 1 and the protruded member 5b formed on a side wall surface 1b are not completely brought into contact with each other but are misregistrated. This smoothes surface pressure and makes it possible to maintain surface pressure high. Therefore, the leakage along the spiral direction of the sealing member 1 can be prevented as much as possible securing and improving the smooth sealing ability and the durability of the sealing member 1 respectively.
