Summary:PROBLEM TO BE SOLVED: To easily increase frictional torque without increasing the number of part items by applying rust preventive oil mixed with a friction coefficient improver to one of a friction surface of at least a rotor or a friction surface of an armature. SOLUTION: In a rotor, a friction surface 8 is formed in a side end part, and rust preventive oil 23 mixed with a friction coefficient improver 21 is applied to this friction surface 8. An armature is coaxially arranged with the rotor by leaving a slight space from the friction surface 8 of the rotor. A friction surface to frictionally engage with the rotor friction surface 8 is formed in the armature as an armature plate. Therefore, generation of rust of the rotor friction surface 8 is prevented by rust preventives 23, and the friction coefficient improver 21 increases a friction coefficient between the rotor friction surface 8 and an armature friction surface by interposing it between the rotor friction surface 8 and the armature friction surface when the rotor and the armature are joined together, and can improve frictional torque.
