A feeding unit of a wire bending machine which improves the shape accuracy of processed articles through accurate transfer of the wire by varying positions of feeding rollers, thereby closely pressurizing a wire is provided. A feeding unit of a wire bending machine comprises: a supporting plate(10) having first and second adjusting members together with auxiliary plates formed at both ends thereof, wherein the first adjusting member has a rod hole formed in an end thereof so that a rod and a pressing spring are inserted into the rod hole; main power transmission means(20) which is installed at one end of the supporting plate, and has a drive gear(22) engaged with a drive gear(G) of a body, a driven gear(24) coaxially interlocked with a second pulley(23), and a tension pulley(26) installed between the drive gear(22) and the driven gear to control tension of a belt(T) together with a distance maintenance bar(25); first and second driven gears(30,30') which are engaged with the driven gear(24) to be rotated together with first and second supporting shafts(32,32'), wherein the first and second supporting shafts are extended to the backside of the supporting plate to have first and second feeding rollers; and third and fourth driven gears(40,40') which are installed oppositely to the first and second driven gears and rotated along with third and fourth supporting shafts(42,42'), wherein the third and fourth supporting shafts are installed adjacently to the drive gear(24), engaged with first and second idle gears, and extended to the backside of the supporting plate to have third and fourth feeding rollers.
