However, such a mounting structure has a problem in that the feeding line support 2 is provided by the elasticity of the tongue 26.
The power supply line support 23 can be attached to the rail 20 so that no "play" occurs in the vertical direction of 3, but the gap S causes a "play" in the left-right direction in FIG. For this reason, when the current collector passes through the portion of the feeder line 27 supported by the feeder line support 23, the feeder line support 23 vibrates and moves due to "play" in the left and right directions. Have. Further, if the power supply line support 23 and the rail 20 are machined so that the above-mentioned "play" does not occur, there is another problem that machining accuracy must be increased and machining efficiency is deteriorated.
