PURPOSE:To lessen the unevenness of driving speed or the drop of driving force by sticking a rotor sliding material with a width easy of sticking, and then, shaving it off excluding the face required for sliding. CONSTITUTION:A sliding material 1 is stuck with a width easy of sticking and enough in sticking strength, and it is shaved off excluding necessary sliding width after its driving face side is stuck to a rotor mother material 2, consequently only the necessary sliding width contacts with an elastic body 3. Therefore, even if the sliding width is thinned fairly, the sliding position ceases to slip. Moreover, since it is shaved off excluding the face necessary for sliding after it is stuck with a width enough in sticking strength, even if the width of the sliding face is thinned fairly, the durability ceases to drop. Hereby, the unevenness of driving speed or the drop of driving force can be lessened. |
