    • PROBLEM TO BE SOLVED: To provide a roll to be used for a drawer of a housing case, which keeps smooth rotation and holds contact friction to a minimum. SOLUTION: Drip-shaped band-like protrusion parts 3 are formed in the direction the same as that of the rotation of a roll 1 on a surface of the roll 1 having shaft holes 2 at both right and left ends, and a catcher 4 is formed at the tip of the drip-shape. Regarding the catcher 4, while a circle is secured in the rotational direction, minute and irregular points are formed in the shape of a fine line, and a contact surface with other body is composed by intermittent points. A stopper 5 to stop the rotation of the roll 1 is formed at the center of the surface, and a rubber material with slight flexibility or a material similar to rubber is used as material.
