Abstract: Disclosed is a bar feeder, which is capable of reliably loading a bar onto a guide rail with a simplified structure. The bar feeder 1 comprises a stock rack 8, a guide rail 4 for guiding a bar to a bar machining apparatus, and a bar supply mechanism 32 for taking bars W one by one out of the stock rack 8 and supplying the taken-out bar W onto the guide rail 4. The bar supply mechanism 32 includes a lifting member 40 adapted to lift a downstreammost one of the bar W on the stack rack 8, a bar receiving member 42 adapted to receive thereon the lifted bar W and supply the bar W onto the guide rail 4, and a stopper member 36 adapted to holds a second-downstreammost one of the bar W to be subsequently supplied. The lifting member 40 and the bar receiving member 42 are adapted to be driven by a common moving device 44, in such a manner that the lifting member 40 is linearly moved in an upward-downward direction in conjunction with a swing movement of the bar receiving member 42.
