The inner swivel fitting 24 is rotatably fitted, and the fluid 25 provided in the swivel fitting 23 passes through the hole 26 drilled in the reel shaft 22 to the fluid provided in the swivel fitting 24. It communicates with the exit 27. an external fluid supply is connected to the fluid population 25;
The inner end of the reeled hose is connected to the fluid outlet 27 .

A hose winding reel 31 is rotatably provided on the mounting board 11, 12 serving as the main body of the device, and a rotating drum 32 is integrally provided on the side surface of this reel 31 via a torque limiter 33. . The reel 31 is made up of a pair of plate members joined together at the center. A recess 35 on the side surface of the reel 31 has a bottom at the joint portion 34.
are formed concentrically, and the rotating drum 3 is placed in this recess 35.
2 are fitted.

The torque limiter 33 has a nut 42 screwed onto a sleeve 41 that is fitted onto the reel shaft 22 and screwed together.
The central part of the disc spring 43 is pressed against the disc spring 43.
A compressive force is applied to the pressing plate 44, and a clamping force is applied between the pressing plate 44 and the plate 45, which is formed integrally with the sleeve 41, and the wear-resistant plate 4 provided between the pressing plates
6 and a disk 47 (!:) provided integrally with the joint portion 34 of the reel 3I, a frictional force for transmitting rotation is applied.

A large diameter rubber belt 51 is provided on the inner peripheral surface of the rotating drum 32.
A small-diameter rubber roller 54, which is integrally fitted to an output shaft 53 of an electric motor 52, is pressed into contact with the large-diameter rubber belt 51. This rubber roller 54 is baked onto the outer peripheral surface of the metal sleeve 55.

FIG. 2 shows a structure for pressing this rubber roller 54,
