ABSTRACT:
A coil winding jig comprises: a first block having a first flange to which the free end of the wire is fixed; a second block having a second flange and disposed opposite to and coaxially with the first block with the front surface of the second flange facing the front surface of the first flange and spaced apart a distance corresponding to the width of the coil to be formed from the front surface of the first flange; a third block disposed coaxially with the second block, having a middle portion contained within the second block, and a coil form having a front end to be pressed against the first flange and projecting from the middle portion through a hole formed in the second flange toward the first flange of the first block. The coil form is tapered toward the first flange, has an outer circumference consisting of inclined side surfaces and is provided with steps having a size smaller than half the diameter of the wire on its side surfaces contiguously with the front surface of the second flange.
