Description of the Related Art Conventionally, a so-called suspension type refueling device, in which a refueling hose is hung from above, has a high-octane gasoline, a regular gasoline, and a light fuel oil above a lane where a vehicle that receives refueling stops. A plurality of refueling hoses hang down corresponding to various types of fuel oil such as, and refueling nozzles are connected to the lower end of each refueling hose. Each refueling nozzle, when not refueling, to avoid contact with the vehicle that has been refueled,
Although the vehicle is stopped at a position of about 1.8 to 2 m from the road surface, if the vehicle has a relatively high vehicle height such as a truck, the operator manually stops the vehicle in order to stop the vehicle near the refueling device main body. The refueling nozzle and refueling hose must be pulled to a position retracted from the lane. Further, even if it is a suspension type, even if it is an oil supply device having a structure in which a nozzle case is provided on the ground, the same problem occurs, and there is a problem that the oil supply work cannot be performed smoothly.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to perform a smooth refueling operation by retracting the refueling hose together with the refueling nozzle from the lane at the time of non-refueling so as to avoid contact with the vehicle that has been refueled. It is an object of the present invention to provide a hose returning device for a suspension type oil supply device capable of performing the above.

[0004]

According to the present invention, there is provided an oil supply hose whose upper end is movably held in the horizontal direction and whose lower end is provided with an oil supply nozzle. In a suspension type refueling device in which refueling is performed in a pulled-out state, when the refueling nozzle is moved from a standby position when not refueling, movement of the upper end of the refueling nozzle is allowed and the refueling nozzle is returned to the standby position. It is a hose returning device for a suspension type oil supply device, which is provided with a hose returning means for returning the oil supply hose that has been pulled out to the oil supply location side in association with the operation.

[0005]

According to the present invention, the upper end of the oil supply hose is movably held in the horizontal direction, and the lower end is provided with the oil supply nozzle. At the time of refueling, the refueling hose is pulled out to a refueling location, and the tip portion of the nozzle is inserted into the refueling port of the vehicle that has received the refueling to perform refueling. When the refueling operation is completed and the refueling nozzle is returned to the standby position, the refueling hose is moved by the hose returning means in the direction of retreating from the refueling location and returned to the initial position. By returning the refueling nozzle to the standby position in this way, the refueling hose can be automatically returned to the initial position, so that the refueling work can be performed smoothly without disturbing the passage of the vehicle that has been refueled. It becomes possible.
