Description

  The present invention relates to a fueling device that supplies fuel oil to an automobile or the like at a fueling station.

In recent gas stations, there have been an increasing number of self-service stations where customers themselves perform refueling operations in order to reduce labor costs. In this self-service station, in order for many unspecified customers to operate the oil supply nozzle of the oil supply device, touching the nozzle grip part and nozzle lever of the oil supply nozzle will keep bacteria and mold attached and maintain a clean feeling. This may be difficult and may cause discomfort. In order to eliminate such an inconvenience, an oil supply device has been proposed in which a gripping part of an oil supply nozzle or a member provided with an antibacterial treatment is provided (for example, see Patent Document 1). In addition, when the customer inserts the discharge pipe part of the fueling nozzle into the fueling port, the static electricity charged on the customer's human body is discharged, causing sparks, which may ignite the fuel oil vapor and cause a fire. was there. On the other hand, the present applicant provides a conductive member in the operation portion of the fueling nozzle so that static electricity charged on the human body or the automobile can be removed before the refueling operation, and this conductive member is installed via the ground wire. The oil supply apparatus connected to the part is proposed (for example, refer to Patent Document 2).
