DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel supply device for supplying fuel oil to an automobile, and in particular, a fuel supply hose suspended from a hose reel provided above a fuel supply area so as to be movable up and down.

[0002]

2. Description of the Related Art A suspension lubricating apparatus has a hose reel provided in a hose processing case provided above a lubricating area, and a lubricating nozzle provided at a lower end of a lubricating hose wound around the hose reel. Then, the hose reel is rotated forward and backward by a rotating device, and the oil supply nozzle is moved up and down between the standby position and the oil supply position. By the way, the motor rotates by inertia even after the power supply is cut off, and the stop position of the refueling nozzle is varied due to the rotation by the inertia. Thus, the rotation due to the inertia of the motor is eliminated. A conventional brake device is a band brake that frictionally contacts a shaft connecting a motor and a speed reducer. Therefore, the structure of the brake device is large and the rotation device is large in structure. Then, the brake pad is easily worn, and when the brake pad is worn, it becomes difficult to apply the brake, and the stop position of the refueling nozzle varies. Also,
The fine powder of the brake pad fluttered and the inside of the case was easily contaminated, and the brake pad needed to be replaced from time to time.
