PURPOSE:To stably manufacture an annular body without the shape dispersion in the peripheral direction by working a long-sized steel wire linearly, feeding by a constant length and cutting it after performing a bending by a work roller. CONSTITUTION:The steel wire 1 wound in a coil shape is linearly shaped by a straight lining roller 4 in a straight lining device A, pinched by the claw 10 of the holding means 9 of a feeding device B and advanced by the fixed distance until its colliding with a stopper 19 by an air cylinder 18. It is then subjected to bending by the bending roller 13 consisting of one set in three pieces of a winding device C by a feeding roller 11, what is made in annular shape by guiding with a guide member 16 so that the tip part may be attained to a winding part 15 is cut at the winding part 15 by the cutting blade 20 of a cutting device D and the annular body 2 excellent in the dimensional and shape accuracies without the dispersion in the peripheral direction length is prepd.
