Abstract:
A coil end shaping apparatus shapes three flatwise bent portions f1 to f3 in a lead wire portion extending from one end of a coil by bringing first and second shaping dies close to each other such that one of the flatwise bent portions is bent in the direction that is opposite to the direction in which the rest are bent. The second shaping die, which is a movable die, has an clearance portion that prevents a portion of the lead wire portion 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 while the flatwise bent portions on the base end side with respect to the flatwise bent portion on the side closest to the free end, of the three flatwise bent portions, are shaped in the lead wire portion.
