PROBLEM TO BE SOLVED: To improve working performance of a spring manufacturing machine. SOLUTION: A rotating casing 26 is rotated around a common center line C1. A final wire rod guide 17 is rotated around the common center line C1. A wire rod feeding unit 12 is reciprocated with an actuating device 53. The actuating device 53 is composed of a motor 55, in which the axial center of a normally-reversibly rotatable rotating shaft 56 is laterally directed, an oscillation arm 57, which is oscillated forward and backward by the motor 55, a protrusion 58, which is provided to the free end of the oscillation arm 57 and made so as to oppose to the center line C1 of a wire rod passage of the final wire rod guide 17, and an annular body 60, which has an annular groove 59 to be fitted to the protrusion 58 and is fixedly fitted to a hollow shaft 48.
