Abstract
The present invention provides a friction resistance generator which can more effectively generate a stable friction resistance. More specifically, according to the present invention, in the configuration where a rotor and a passive member face each other in a radial direction through a plurality of rollers, a rolling axis of each roller is made to be in a range larger than an angle of 5.degree. and smaller than an angle of 20.degree. with respect to a rotational axis of the rotor, and the rolling axis of each roller is made to be in a range larger than an angle of 25.degree. and smaller than an angle of 90.degree. with respect to a plane including the rotational axis of the rotor. Thereby it is possible to always generate an effective and stable frictional force.
