PROBLEM TO BE SOLVED: To use various kinds of winding rolls and hardly damage the winding rolls.SOLUTION: A winding device 1 of a belt-like body S includes: a pair of roll holding members 5 for holding both ends in an axial length direction in a cylindrical winding roll R to wind the belt-like body S; and a fixing member 7 for fixing a tip section Sa of the belt-like body S to the winding roll R. The winding roll R is rotationally driven via the roll holding members 5 so as to wind the belt-like body S. Each of the pair of roll holding members 5 includes a projection, and each projection is loosely fitted to openings at both ends of the winding roll R so as to relatively rotatably hold the winding roll R. The fixing member 7 is arranged to connect the pair of roll holding members 5 via an outer peripheral surface of the winding roll R. When the one roll holding member 5 is rotationally driven in a state that the tip section Sa is inserted between the fixing member and the outer peripheral surface of the windi
