Further, although not shown, a closing roller that is pressed against the surface of the lid member 4 is provided on the outer side of the opening roller 20 in the moving direction, so that the protrusion 6 is engaged with the engaging groove 5.

Thus, when installing the current collector 14 on the power supply trolley, the lid member 4 is opened only partially in advance, and the current collector 17 is inserted into the groove 3 in this opened part to bring it into the state shown in the figure.

When the vehicle is running, the opening roller 20 of the current collector 14 opens the lid member 4 so that the current collector 17 can collect current, and after the current collector 17 has passed, the aforementioned closing roller supplies electricity to the protrusion 6 of the lid member 4. It is elastically engaged with the engagement groove 5 of the trolley body 1, and the power supply line 2 is hermetically sealed.

According to the above configuration, the opening roller 20 of the current collector S
and the support plate 32 supporting the current collector are disposed directly opposite each other, and the lid member 4 opened by the opening roller 20 is brought close to the support plate 32, so that the current collector traveling vehicle M
When the current collector S is tilted and displaced with respect to the vehicle M and the shaft 16 due to an irregularity of the power supply trolley W when it approaches an enclosure (curve) or a branch part of the power supply trolley, the cover member 4 and the support plate 32
There is a problem in that the current collector S may interfere with the end E of the power supply trolley W, causing damage to the cover member 4 made of a soft material, or, in severe cases, causing the current collector S to separate from the power supply trolley W.

The present invention was made in view of such conventional problems.
A current collector for a current collecting traveling vehicle that solves the above problems by installing a guide member that guides the lid member of the power feeding trolley between an opening roller that opens the lid member of the power feeding trolley and a support plate that supports the current collector. The purpose is to obtain.
