PURPOSE: A power transmission structure of a feeding roller constituting a spring forming apparatus is provided to prevent damage to a specific feeding roller due to a concentrated load. CONSTITUTION: A power transmission structure of a feeding roller constituting a spring forming apparatus comprises a feeding box(210), two pairs of feeding rollers(220), a first gear(230), a first transmission unit(240), and a second transmission unit(250). The feeding box connects to the rotating unit to be rotated. The feeding rollers are coupled with the upper end of the shaft supported by a bearing. The first transmission unit comprises a second gear(242) and a vertical bevel gear(243). The second gear is formed at the upper end of a first middle shaft(241) passing through the bottom of the feeding box. The vertical bevel gear is coupled at the bottom of the first middle shaft. The second transmission unit comprises a horizontal bevel gear(253) and a third gear(252). The horizontal bevel gear is formed on one side of a second shaft(251) formed on the lower surface of the feeding box. The third gear receives the power transmitted through the rotation unit.
