PROBLEM TO BE SOLVED: To provide an inexpensively manufactured takeup roller capable of easily removing a belt-like roll.SOLUTION: A takeup roller 3 includes a columnar roller body 10 having a groove part 11 formed in an outer peripheral surface to extend in an axial direction, a bar-like holding part 21 insertable into the groove part so that a part thereof can project from the outer peripheral surface, and rotation regulation means 30 for regulating the rotation of the holding part with respect to the groove part in the inserted state of the holding part into the groove part. The holding part has a holding portion 22 for holding a peeling mount with the groove. The holding portion is formed into a shape in which in a section orthogonal to the axial direction of the holding part, the size of a first direction orthogonal to the axial direction is set longer than that of a second direction orthogonal to the axial direction and the first direction. The rotation regulation means regulates the rotation of the holding part with respect to the groove part so as to hold the first direction in the holding portion in the radial direction of the roller body.SELECTED DRAWING: Figure 1 |
