摘要： A coil end shaping apparatus 20 shapes three flatwise bent portions f1 to f3 in a lead wire portion 11 extending from one end of a coil 10 by bringing first and second shaping dies 21 and 22 close to each other such that one (f1) of the flatwise bent portions is bent in the direction that is opposite to the direction in which the rest (f2 and f3) are bent. The second shaping die 22, which is a movable die, has an clearance portion 230 that prevents a portion of the lead wire portion 11 to be bent along the flatwise direction on the side closest to the free end from being restrained by not contacting the lead wire portion 11 while the flatwise bent portions f1 and f2 on the base end side with respect to the flatwise bent portion f3 on the side closest to the free end, of the three flatwise bent portions f1 to f3, are shaped in the lead wire portion 11.
