Claims

[Claims for Utility Model Registration] A roll support part that supports a roll around which a sheet material is wound, the whole having a cylindrical shape, the inner surface being at least partially inclined with respect to the outer surface, and being fitted into the end of the roll. a support shaft comprising a support part, and a tapered part corresponding to the inclination of the support part on the distal end side, which can be press-fitted from the axial direction to expand the support part, and is pressed against the proximal side. a restraining member comprising a receiving portion; a pressing means provided on the outer frame and in pressure contact with the pressure receiving portion and capable of pressing the restraining member in the insertion direction; and a pressing means interposed between the support shaft and the restraining member. A roll support section comprising: a biasing means for biasing the restraining member in the opposite insertion direction with a force weaker than the pressing force.
