Abstract

PURPOSE:To obtain a sure shut-off condition with a small closing force by forming convex spherical surfaces respectively on a movable permanent magnet and on a part of at least one of attracted support members attracted and supported by the movable permanent magnet. CONSTITUTION:An attracting and supporting member 14 having a convex spherical surface 13 is attracted by a permanent magnet 12 at one end face of the latter. A valve element 15 made of nitrile rubber and formed in a spherical shape is provided at the other end of the attracting and supporting member 14. A metal ring 23 is attracted to the outer periphery of that part of the movable permanent magnet 12 which abuts against the attracting and supporting member 14 so as to form a raised stepped part which prevent the convex spherical surface of the attracting and supporting part from shifting from the center of the movable permanent magnet 12. With this arrangement, the spherical attracting part is slid and rotated lightly and smoothly, thereby it is possible to prevent the valve element 17 from giving an unreasonable contact pressure to the valve seat.
