In order to disengage the shaft 19 from the cylindrical body 10 while the arm 2 is rotated to a position where the current collector 4 can be retracted from the insulated trolley wire 28 within the rotation range of the arm 2, the shaft 19 can be detached from the cylindrical body 10. The insertion length is set to the maximum retreat distance or less. The maximum retreat distance in the embodiment depends on the position where the current collector 4 contacts the insulated trolley wire 28 and the end 5a of the mounting plate 5 when the arm 11 rotates in the retreat direction B as shown in FIG. It is the distance from the position of the current collector 4 in the stopped state, and the insertion length of the shaft 19 is the size.

Further, the shaft 19 is detachably inserted into the tubular body 10 by the split 21 and the hook 20, but the shaft 19 is not limited to this and may be attached by a screw or the like. Further, although the arm 2 is a parallel arm in the embodiment, it may be a single arm.
