Abstract
First and second flanges protrude from a shaft portion in a direction crossing an axial direction. The first and second flanges define a position of a roll fitted to the shaft portion in the axial direction. First and second facing surfaces face the roll. First and second contact portions protrude from the first and second facing surfaces in the axial direction. The first and second contact portions are configured to contact a paper tube. A screw member is rotatable relative to the shaft portion, the first flange, and the second flange, thereby changing a relative position of the first flange and the second flange between a hold position at which the first and second contact portions press and hold the paper tube in the axial direction and a separation position at which at least the first contact portion or the second contact portion is separated from the paper tube.
