A guide portion for guiding the hose is provided, and the width dimension of the opening portion is set to an arch shape that decreases as it goes upward, while the drum is wound around the outer peripheral surface. The drum portion is configured by a barrel portion and flanges provided at both ends of the barrel portion, and the drum portion is disposed on a frame provided with the guide portion, with the barrel portion in a horizontal direction and opposed to the opening portion. A concave and convex surface having a ridge-like concavo-convex shape for reducing frictional resistance caused by contact with the hose was formed by subjecting the inner side surface of the ridge portion to warping.
[0011]
For this reason, the frictional resistance which arises in the hose and collar part which concentrate on the collar part side of a drum edge part when winding is reduced, and the winding spot of the hose to the said drum is prevented.
[0012]
It should be noted that the ridge-shaped uneven surface may be set on each of the inner side surfaces of the both flange portions or only on one side.
[0013]
Furthermore, in the hose reel according to claim 2 , the drum is rotatably accommodated in a case-like main body case constituting the frame, and the inner side surface of the main body case is subjected to a boring process so that the hook-like reel is formed. An uneven surface was set.
