The insertion hole 2 of the terminal fitting 1 until the terminal part 2 is bent
It is possible to effectively prevent the occurrence of escape from 3. Also,
As shown in FIG. 4, when manufacturing the terminal fitting 1, conventionally, first, an intermediate process product 2 of the terminal fitting body is manufactured.
9 was manufactured in advance by continuously forming the parts 29 and cutting the intermediately processed product 29 as appropriate.
In order to avoid manufacturing errors during cutting, the so-called "feeder 30" portion was to be discarded. However, in the terminal fitting 1 used in the terminal structure according to the present embodiment, the portion of the feeder 30 can be effectively used as the engagement piece 15 of the terminal fitting 1, improving the material usage efficiency. It is possible to do so.
尚、端子金具１の具体的形状については本実施
