A roll holder includes a shaft portion configured to hold a roll member formed by winding a strip-shaped material. A pair of wall portions is configured to restrain axial movement of the roll member held by the shaft portion. Also, a reduction unit is provided in the roll holder to reduce frictional resistance against a force by which the strip-shaped material is drawn from the roll member whose axial movement is restrained by the wall portions. |
