Abstract
In a refrigerant circuit component or valve device, the present invention projection-welds a connector to a cap member and prevents intrusion of spatter into a refrigerant circuit. A-cylinder section in which an inside hole of the connector is open is inserted in an inside hole formed in the center of the cap member. The area between the A-cylinder section and a projection of the connector is used as a spatter generation space. The projection of the connector abuts against the cap member and is projection-welded to form a welded part. The open end of the inside hole of the A-cylinder section is crimped to pressure-join the open end to the open end of the inside hole of the cap member. Spatter is sealed inside the spatter generation space. A portion of the surface layer to which the generated spatter adheres may be removed by machining to provide a spatter-removed structure.
