荷クラッチ。An overload clutch for transmitting limited torque between two coaxially disposed drive parts, and a ball that protrudes beyond the outer diameter of the second drive part of the drive part is disposed on the circumference of the second drive part. A bushing ring is disposed on the outer peripheral end of the first drive part of the drive part, and the bushing ring is disposed on the end surface of the second drive part to press the ball so as to keep the two drive parts connected at all times. A filter load clutch is provided with a thrust washer that supports the thrust load of the first drive unit and the pressing load of the ball.
