<p>PROBLEM TO BE SOLVED: To easily change the transmitted torque value by pressing a drive side friction member to be integratedly rotated with a drive side rotating body against a driven side friction member to be integratedly rotated with a driven side rotating body to change the pressure. SOLUTION: When the driving current is supplied to an electromagnetic coil 49 by a driving means, a drive side rotating body 40 is attracted by a fixed core 48, the rotating body 40 presses a drive side friction plate 45 against a driven side friction plate 43, and is stopped where friction plates 43, 45 are abutted on each other. The rotating body 40 is not closely attached to the fixed core 48, but opposite to each other with a gap (g) left behind. The rotation from a rotating means is transmitted to a driven side rotating body 41 through the driven side friction plate 43. In a case of the torque of not less than the prescribed value, a slip is generated between the friction plates 43, 45, and not rotational force is transmitted. The magnitude of the force with which the friction plate 45 presses the friction plate 43, is determined by the magnitude of the current into the electromagnetic coil 49, and can be set by the driving means, and the transmitted torque value necessary for a torque limiter can be easily changed.</p> |
