Abstract
A vibration-proof spring, which coaxially inserts a shaft, is provided in a body of a control valve. The vibration-proof spring includes a cylindrical spring body, spring parts, which are integrally formed with a side wall of the spring body and are supported by the spring body in a cantilevered manner, and bulging portions, which are formed, on surfaces of the spring parts facing the shaft, in a protruding manner. The spring body is formed as a cylindrical body such that a plate-like body, which is obtained by punching a metallic plate through a press-forming process, is bent along a longitudinal direction of the plate-like body. Also, the spring body is formed in such a manner as to have edge parts that protrude radially outward from at least one of ends of the cylindrical body in the direction of axis line.
