PURPOSE:To reduce energy loss by composing clutch means of a drive clutch plate, a driven clutch plate, an electromagnetic coil, and magnetic powder, thereby preventing a clutch from heating. CONSTITUTION:The first and second shafts 2, 3 are disposed on the same axis in a case 1, and are rotatably supported via bearings 11-14. A reduction gear 8 made of planetary gear mechanisms 6, 7 and an electromagnetic powder clutch 9 are contained in the case 1. The clutch 9 is formed of a drive clutch plate 9a secured to the shaft 2, a driven clutch plate 9b secured to the shaft 3, an electromagnetic coil 37, and magnetic powder 35 sealed in a space between the plates 9a and 9b. |
