Abstract
A conductor wire crimping portion () has depressions () that are disposed at prescribed intervals in the axial direction and that are linear locking portions. The depressions () are continuously depressed grooves on the inner surface of a crimping portion (). On an upper die (), at a portion corresponding to the conductor wire crimping portion (), a straight portion is formed, and in the front-back direction thereof, tapered portions are formed. More specifically, the upper die () is formed to have an inverted trapezoid shape, a middle portion of which protrudes in the crimping direction. Consequently, at each boundary between the straight portion and the tapered portion, a die angled portion () is formed. At an area corresponding to the straight portion of the upper die (), the depression () is provided, and at an area corresponding to the die angled section (), the depression () is provided.
