A silencer for oxygen generator which is constructed to reduce a noise generated from an suction port or an exhaust port is provided. A silencer(1) for oxygen generator comprises: an inner pipe(10) of which one end portion is closed, and which has an outflow hole(11) formed in the other end portion thereof and a plurality of micro-holes(13) formed in a side face thereof; a flange(20) which is integrally formed on an outer peripheral surface of the outflow hole, and of which a connecting part(23) extends toward the inner pipe; and an outer pipe(30) which has a connecting part(33) formed on one end portion thereof such that the connecting part(33) is connected to the connecting part(23), and an inflow hole(31) formed in the other end portion such that the inflow hole has a smaller diameter than that of the closed one end portion of the inner pipe, wherein a non-woven fabric(40) is inserted between the inner pipe and the outer pipe. |
