PROBLEM TO BE SOLVED: To provide a terminal end structure of a rigid electric train line which cushions shocks due to collision of a pantograph, and comparatively facilitates an installation construction. SOLUTION: A T-shaped frame 2 has a flange 7, and a web 8. An ear 2 is fixed along a bottom edge of the T-shaped frame 2 with bolts/nuts 5, 6 to sandwich a trolley wire 4. The bottom end of the web 8 moves upward like an arc from a predetermined position near a terminal end to the terminal end, and the web has an opening 8b with a predetermined longitudinal width near it. A nipping part 9 along the bottom end of the web 8 has projection bars 10, 11, below which a nipping pawl 13 fitted in a bar groove 14 of the trolley wire 4 is located. A plurality of bolt insertion holes 12 penetrate through the web 8. An ear 3b has projection bars 15, 16, a bolt insertion hole 17, and a nipping pawl 18. The projection bar 15 projects in contact with one side of the web 8 on its tip, and extends in parallel to the projection bar 10. The projection bar 16 extends in parallel to the projection bar 15. The bolt insertion hole 17 penetrates through the ear 3b between the projection bars 15 and 16. The nipping pawl 18 is fitted in the bar groove 19 of the trolley wire 4. COPYRIGHT: (C)2008,JPO&INPIT
