PROBLEM TO BE SOLVED: To provide a pin feeding device which can feed fixing pins to a gun head with extreme ease. SOLUTION: The pin feeding device comprises a pin feeding room 1 with a pin discharging hole in which a plurality of fixing pins B are stored, a guide cylinder 3, a transfer piston 4 which is loosely fitted in the guide cylinder and transfers the fixing pins B to the gun head, and an elastic member which urges the transfer piston elastically from the guide cylinder 3 forward to the projection direction. When the transfer piston 4 is pushed in against the elastic urging force of the elastic member, a pin loading groove and the pin discharging hole fit together to load the fixing pin B into the pin loading groove. When the transfer piston 4 is projected and then pushed back again, the fixing pin in the pin loading groove is restrained from retracting backward by a stopper so that it is thrust forward from a pin projection hole.
