<P>PROBLEM TO BE SOLVED: To secure electric connection reliability even when a defect appears in a bolt fastening form. <P>SOLUTION: A retention mechanism 30 for holding two connection plates 15 in a superposed state is provided between the two connection plates 15 vertically overlapping each other. A contact piece 40, which has a top surface provided with a contact protrusion 41 and which can be elastically bent in a vertical direction, is formed in the lower-side connection plate 15 in such a shape as to be housed in a storage hole 43 formed in the state of penetrating the connection plate 15. The contact piece 40 has a structure in which a lowermost end position of the contact piece 40 remains in the storage hole 43 even when an upward protruding end of the contact protrusion 41 is displaced by being bent downward up to a position flush with an upper end surface of the storage hole 43, while the contact protrusion 41 protrudes above the upper end surface of the storage hole 43 in a natural state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
