Since the small-diameter portion or the large-diameter portion is set to have a wall thickness that can withstand the caulking force acting in the radial direction or the like, the caulking does not affect the valve seat. Further, the housing member after the valve member is inserted and caulked is press-fitted into the conduit of the fluid device. At the time of this press-fitting, in the configuration in which the valve seat is arranged in the small diameter portion, the small diameter portion is axially separated from the large diameter portion, so the valve seat may be affected by the radial load. Absent. Further, when the valve seat is arranged in the large diameter portion, the large diameter portion is set to have a wall thickness that can withstand press-fitting (radial load), so that the valve seat is not affected by the radial load.
