In a roller member where a rotary shaft (110) is inserted through a through-hole (111) of a roller part so that the roller part is removably mounted on the rotary shaft, the rotary shaft is provided with a positioning retention part (121) for retaining one end of the roller part. Further, the rotary shaft is provided with an engagement recess (123) at place on its portion outward of the other end of the roller part. An engagement protrusion (117) is provided at a snap fit portion (116) extended axially outward from the other end of the roller part. In a state where the snap fit portion is elastically deformed in a direction opposite to the extension direction, the engagement protrusion is engaged with the engagement recess. |
