ジ供給装置。[Scope of Claim for Utility Model Registration] A rotating magazine with a plurality of screw receiving holes arranged around its periphery and rotatably supported by the main body of a screw tightening machine, and a ratchet-shaped gear body that is linked to the rotating shaft of the rotating magazine. a rotational drive mechanism that reciprocates a pawl member in a tangential direction and, at this time, engages the pawl member with a pawl-like gear body to intermittently drive the rotating magazine; Air jet nozzles are arranged at opposing positions, and an end of a pipe communicating with a nose section provided at the tip of the screw tightening machine body is arranged at a position facing the other end of the screw receiving hole, and the air jet nozzles are arranged at positions facing each other. A screw feeding device for a screw tightening machine, comprising: a screw feeding mechanism that blows air from a nozzle to feed the screws in the accommodation hole to the pipe; and an operating means that drives the rotational drive mechanism and the screw feeding mechanism. .
