To improve a spring processing performance, a spring manufacturing machine is structured such that 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 moved forward and backward by an actuating apparatus (53), and the actuating apparatus (53) is constituted by a motor (55) which has a reversible rotation shaft (56) with an axis directed to the lateral direction, an oscillating arm (57) which is oscillated forward and backward by the motor (55), a projection (58) which is provided in a free end of the oscillating arm (57) and opposes to the center line (C1) of a wire rod passage of a final wire rod guide (17), and an annular body (60) which has an annular groove (59) fitted to the projection (58) and is fitted to a hollow shaft (48).
