  According to a second aspect of the present invention, in the first aspect of the present invention, the winding portion is curved in an involute curve shape, and both ends thereof are spaced apart from each other in the radial direction, and the distance between the winding portions is the same as that of the suction hose. It is set substantially equal to the diameter, and when the string-like object is wound around the winding part, one end of the suction hose is located between both ends of the winding part.

According to the invention of claim 1, when the hose reel is rotated in a state where the hook is engaged with one end of the suction hose, the string-like object to which the hook is attached is wound around the winding portion of the hose reel. Subsequently, the suction hose is wound and stored along the winding portion. Therefore, when pulling out the suction hose during use, it is only necessary to engage the hook hanging from the hose reel with one end of the suction hose and to rotate the hose reel. Moreover, since the suction hose is pulled by the string-like object, even if vibration during traveling is transmitted, the suction hose is not loosened and a stable winding state can be secured .
