Abstract
A check-valve fixing structure includes a base body formed with a passage in which a check valve is inserted, a receiver formed in the passage, and a flange formed with a socket member of the check valve and engaged with the receiver when the check valve is inserted in the passage. With the flange being placed on a valve-seat member of the check valve and abutting on the receiver, the base body is crimped at an opening end of the passage to fix the socket member and the valve-seat member to the base body.
