PROBLEM TO BE SOLVED: To reduce friction sound and abrasion during rolling a roller as much as possible. SOLUTION: This roller is provided with a roller body part RH, outer circumferential parts D1G and D2G integrated with the roller body part so as to be prevented from separating therefrom and slightly projecting to the outer circumferential surface RHG of the exposed roller body part, and elastic parts D1 and D2 formed of a member being softer than the roller body part and having elasticity.
