特徴とするロール支持軸の構造体。 In a structure in which a support shaft is moved from both ends to allow a roll body for winding paper, film, etc. to be attached and detached, a spring action is formed by punching and bending the cylindrical collar inside the roll body. A protrusion having a shape is integrally formed on the collar, and a protrusion having a fine triangular tooth shape such as a knurl is provided on the outer peripheral surface of the support shaft so as to engage with the protrusion.
Further, a structure of a roll support shaft characterized in that a shaft diameter portion slightly smaller than the inner diameter of the collar is provided at the base portion where the collar is inserted, and the triangular tooth-shaped protrusion is integrally configured to lock rotation of the roll body. .
