TORQUE TRANSMISSION DEVICE, KNEE JOINT AUXILIARY DEVICE AND ECOLOGY MOTION TRAINING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a torque transmission device, a knee joint auxiliary device and an ecology motion training device in which limitation on compact-size and light weight formation can be restricted.SOLUTION: This invention comprises a planetary gear mechanism 21, a clutch part 23, a clutch case 51 and a hub part 65. There are provided the clutch case 51 storing the clutch part 23, engaged therewith in a rotating direction and connected in conduction therewith and the hub part 65 provided at a sun gear 29, engaged with the clutch part 23 in a rotating direction thereof and connected in conduction therewith. The clutch part 23 includes an outer plate and an inner plate supported individually at the clutch case 51 and the hub part 65 and oppositely arranged in an axial direction and an adhering sheet placed between the outer plate and the inner plate so as to control a torque transmittance between both plates through electrical energization control with both plates being applied as electrodes. The adhering sheet has dispersed ER particles on an electrical insulation medium and the ER particles are movably controlled through electrical energization control.SELECTED DRAWING: Figure 7
