ABSTRACT:
A check valve for an air chamber of an air suspension mechanism in which a shock absorber is surrounded by a housing and an elastic body to form the air chamber, includes an air supply tube, a connector welded airtightly to the housing and having on an outer peripheral surface a first thread and on an inner peripheral surface a second thread respectively, a valve body formed of a rubber to converge inward of the housing and having in an inner end a slit, a nut screwed onto the first thread of the connector to fix the valve body to the connector and a mounting nut screwed into the second thread of the connector to removably connect the air supply tube to the connector. The slit of the valve body is expanded by the air supply tube after a thread of the mounting nut is engaged with the second thread of the connector in one or a few screw threads.
