[0002]

2. Description of the Related Art Conventionally, fuel oil supplied by a fueling device installed in a gas station is highly flammable, and is ignited by static electricity charged on a human body or an automobile, causing a fire. There was a fear. In order to prevent this, the workers at the gas station wear the conductive clothes and shoes to carry out the fueling work. In addition, the static electricity charged in the automobile escapes via the discharge pipe of the fueling nozzle which is entirely made of conductive metal.

[0003]

By the way, in recent gas stations, a self-service type oil supply apparatus is installed in which the customer himself / herself performs an oil supply operation for the purpose of reducing labor costs. Workers at the gas station wear clothes and shoes that remove static electricity, but the customer does not make any preparations for them, so sparks caused by static electricity charged on the human body are generated from the fueling device. There was a risk of igniting the vapor etc. and causing a fire. Further, since the grip portion of the oil supply nozzle is formed of a non-conductive synthetic resin in order to improve the operability and reduce the manufacturing cost, the charged static electricity may not escape easily.

The present invention has been made in view of the above circumstances.
An object of the present invention is to provide an oil supply device capable of reliably removing static electricity charged on a human body or an automobile before refueling work and preventing accidents such as a fire.

In a refueling device that is equipped with a data input / output device for inputting / outputting refueling setting data, the customer himself / herself performs refueling setting by the data input / output device and refueling work by a refueling nozzle. A conductive member is provided in the portion, and the conductive member is connected to the installation ground portion via a ground wire. Static electricity charged on the human body or automobile before the refueling operation can be reliably removed by discharging it from the conductive member provided in the operation part of the data input / output device or the refueling nozzle to the installation ground part through the ground wire, Accidents such as a fire can be prevented.

According to a second aspect of the present invention, the data input / output device is characterized in that the surface of the operation button is formed of a conductive member. Static electricity can be easily removed by operating the data input / output device.

According to a third aspect of the present invention, the oil supply nozzle is characterized in that a conductive member is attached to a grip portion thereof. Static electricity can be easily removed by operating the fueling nozzle.
