Abstract
This valve device includes: a housing including a valve port located on one side in an axial direction and through which gas flows, and a valve chamber connected to the valve port; a guide disposed in the valve chamber and including a guide body that is cylindrical and a plurality of supports that extend outward from an outer peripheral surface of the guide body and abut an inner peripheral surface of the valve chamber; and a valve body inserted into the guide body and configured to open and close the valve port. One end of the guide body is spaced apart from the housing in the axial direction.
