PROBLEM TO BE SOLVED: To provide a valve capable of suppressing a valve shaft from oscillating in a clearance present between the valve shaft and a bearing portion.SOLUTION: An annular member 15 is formed to have a larger inside diameter as being closer to a bearing portion 3 and includes an inclined inner circumferential surface 15b. An urging force in a direction of the bearing portion 3 applied from a spring 11 to the annular member 15 is transferred to an O-ring 14 via the inclined inner circumferential surface 15b, so that the O-ring 14 is pressed against a valve shaft 4 and the bearing portion 3.SELECTED DRAWING: Figure 2 |
