The present invention is to provide a member for reducing charge for transportation that further decreases positive charge of charged transportation to contribute to improvement in driving stability and acceleration performance. The member for reducing charge for transportation 1 of the present invention is a laminated structure in which a metal layer 11 and a radiation generating layer 12 are laminated. The metal layer 11 contains a metal with a redox potential of 0 V or less or an alloy of a metal with a redox potential of 0 V or less, and the radiation generating layer 12 contains a mixture of a natural ore containing a radioactive substance with a radiolucent resin. The dose of radiation generated from the radiation generating layer 12 is from 0.02 Sv/h or more to 0.2 Sv/h or less. The member 1 is suitably used for the transportation in which the body is positively charged by static electricity caused by travelling, cruising, etc.

A utility vehicle includes a chassis and a centrally-mounted ground-rod driver system. The chassis presents a central area. The centrally-mounted ground-rod driver system is secured to the chassis at the central area. The centrally-mounted ground-rod driver system includes a ground-rod, a driver assembly configured to drive the ground-rod into an underlying surface under the chassis, and a grounding cable associated with the ground-rod so as to allow an electrical discharge through the grounding cable, through the ground-rod, and into the underlying surface. The ground-rod is driven in beneath the central area of the chassis such that a radius of electrified ground of the underlying surface is away from a utility worker.

An electrostatic eliminating device comprises an electrostatic input terminal, an electrostatic absorption circuit, an electrostatic output terminal. The electrostatic absorption circuit is configured to absorb static electricity accessed to the input end of the electrostatic absorption circuit. The electrostatic input terminal is connected with the door handle, and the electrostatic output terminal is connected with the door handle or the human body to form a circuit, so that the electrostatic ab sorption circuit can absorb the incoming electrostatic charges to avoid the concentration of electrostatic charges on the door handle, which may cause the user to feel electric shock when touching the door handle.
