  • Publication number: 20170222339
    Abstract: A ground terminal fitting includes a bolt fastening portion (11) to be bolted to a ground part (40) and a wire connecting portion (12) to be connected to an end part of a wire (30). The bolt fastening portion (11) and a bottom plate portion (18) of the wire connecting portion (12) are arranged flush with each other. A protrusion (21) projecting toward the ground part (40) is provided on a part of the bolt fastening portion (11) around a bolt insertion hole (14) through which a bolt (41) is to be inserted. Since a linking portion (13) lining the bolt fastening portion (11) and the wire connecting portion (12) needs not be formed into a bent shape according to this configuration, a stress concentration on the linking portion (13) can be alleviated.
