<P>PROBLEM TO BE SOLVED: To perform attaching of an ear body surely and easily without causing an impact sound using existing tools, by reducing the number of components as a whole for improved work efficiency. <P>SOLUTION: Under such a condition as a trolley wire TR or both the trolley wire TR and a stranded wire YR are held safely and surely by a relatively simple operation, this device is used by being attached to various pieces of metal hardware for an electric car line, including a pull-off for an electric car line, a steady brace, and a hanger bracket hanging from an overhead wire. Ear bodies 21 and 22 in right and left are built in a cap body 10 as one body. The trolley wire TR and the stranded wire YR are interposed between a pinching part of both the ear bodies 21 and 22, and then, the cap body 10 is rotated in the axial direction, so that cams 11Y and 11Z press both the ear bodies 21 and 22 inward, thereby strongly keeping the holding state relative to the trolley wire TR and the stranded wire YR. <P>COPYRIGHT: (C)2012,JPO&INPIT |
