The sealed space 34 is sealed from the outside except that it communicates with the outside through a fine clearance which is defined between the outer peripheral face of a valve element 4 and the inner circumferential face of a sleeve 33 and indispensable for a slide of the valve element 4. A path hole 43 having an orifice 44 is formed inside the valve element 4. The path hole 43 is opened only to the upper and lower ends of the valve element 4.
