PURPOSE:To lessen load on a driven bearing by disposing a sealed case on the rotating driving side and a driven disc on the driven side, respectively to reduce the weight of the driven side. CONSTITUTION:A driven disc 8 fixed to the trailing end portion of a rotating member 5 positioned in a sealed case 2 retains a torque transmission clearance 7' between one side surface or an outer peripheral end surface and a confronting inner peripheral surface of the sealed ease 2 side. The sealed case 2 is formed on the rotating driving side, and the rotating member 5 fitted with a cooling fan as the driven side is supported on a shaft center opening portion 3 of the front wall portion of the sealed enclosure side through a bearing 4. Further the driven disc 8 is disposed on the driven side. Accordingly, the driven side can be formed to be very light so as to lessen load placed on the bearing 4.
