PURPOSE: A relief valve structure for hydrogen compressor is provided to the damage and abrasion of housing inlet due to frequent reciprocating motions by reducing the closing speed of an inlet. CONSTITUTION: A relief valve structure for hydrogen compressor comprises an inlet(20), an outlet(21), an elastic member adjusting screw(30), a valve member(50), and a cushion ring(60). The elastic member adjusting screw is fixed and coupled in one end of the housing. An elastic member(40), which is built-in in a housing, is connected to the other end of the elastic member adjusting screw. One end of the valve member is put in the elastic member. The other end of the valve member is touched with the inlet to open and close the inlet. The cushion ring reduces an oil flow path of the inlet.
