Abstract

PURPOSE: To ensure sealing of a cylindrical part by tightening the cylindrical part of a sealing member evenly by a rigid bush on the inside and a wall of end member.
CONSTITUTION: The sealing member 17 is formed of a ring-shaped part 18 and the cylindrical part 19. The cylindrical part 19 is located intermediately in a part surrounding a valve shaft 12 and a supporting shaft 16. The bush 20 is formed of rigid material such as metal and located intermediately between the inside of the cylindrical part 19 and the valve shaft 12 and the supporting shaft 16, respectively, inside the part 16. Accordingly, the bonding force of the end members 2 and 2' act as the force tightening the cylindrical part 19 evenly since the rigid bush 20 is located intermediately inside the cylindrical part 19 of the sealing member 17, whereby the sealing at this part is ensured.
