PROBLEM TO BE SOLVED: To provide a spring manufacturing apparatus whose arrangement angle can optionally be changed independently of tool supporting mechanisms without providing a servomotor as a driving source per tool supporting mechanism, and to provide a driving force transmission part mounted on the apparatus. SOLUTION: The slide operation of a tool mounted on each tool unit 400A, 400B and 400C is realized by a single ring gear 10 arranged at a forming table 200 as a common driving source to all the tool units, and a cam shaft block 20 transmitting the torque of the ring gear 10 to each tool unit 400A, 400B and 400C. The cam shaft block 20 is constituted as the body separated from the tool units 400A, 400B and 400C, and its arranging angle in the surface of the forming table 200 is constituted so as to be changeable independently of the tool units 400A, 400B and 400C.
