<p>PROBLEM TO BE SOLVED: To provide a clutch of which the operation is stabilized by preventing oil transmitted along a shaft from entering. SOLUTION: One of features of this invention is that the clutch for controlling the on/off switching of the rotation by impressing a voltage is formed on its one or both ends with the film of oil repellent material. This means that the bearing side of the clutch and the opposite side thereof are coated by a silicone-or fluorine-based oil repellant. In this way, the oil transmitted along the shaft can be prevented from entering into the clutch.</p> |
