There is a problem that the operability is deteriorated and the refueling work is hindered.

In addition, since the customer himself / herself operates the refueling nozzle in the refueling device installed in the self-service station, a means for preventing the influence of ultraviolet rays on the human body is required. In the invention described in Patent Document 1, ultraviolet rays are intermittently irradiated (irradiated or not irradiated), but this is intended to prevent the life of the light source lamp from being shortened, and is inside the apparatus. It is not a means to prevent the effects on the human body when the hands are touched.

The present invention has been made in view of the above-mentioned problems in the prior art, and provides a refueling device having excellent operability and safety while quickly and easily inactivating a virus or the like by using ultraviolet rays. With the goal.

Further, the conventional refueling nozzle can be used as it is.

Further, the nozzle hook is provided with an openable / closable cover portion that covers the refueling nozzle, and the irradiation portion that the optical fiber irradiates ultraviolet rays emits ultraviolet rays to the reflecting means provided on the surface of the cover portion that faces the refueling nozzle. Can be irradiated. Since the ultraviolet rays are directly reflected and reflected by the reflecting means and irradiated to the refueling nozzle, the sterilization efficiency is improved. Further, since the ultraviolet rays are not emitted to the outside by hooking the nozzles, the influence of the ultraviolet rays on the human body can be suppressed, and the conventional refueling nozzle can be used as it is.

Further, the optical fiber can be wound around the refueling nozzle, a part of the clad of the optical fiber can be removed, ultraviolet rays can be derived from the removed portion of the clad, and the surface of the optical fiber can be covered with a transparent member. .. This makes it possible to sterilize the refueling nozzle while using the conventional nozzle hook.
