Abstract
A mechanism of a simple structure, in which always stable and discretionary frictional resistance can be produced even when the speed of rotary movements or rectilinear movements of the subject structure changes and, moreover, the magnitude of the frictional force can be easily controlled by changing the magnitude of a load. Namely, when a rotary member 1 is rotated while a load toward the axial direction is being applied, numerous rollers 2 make rolling motions in contact with the rotary member 1 and a passive member 3. The rollers 2 make rolling motions along a track of rotation of the rotary member 1. The rollers 2 are restrained to roll toward a direction being inclined by a prescribed angle by a cage 4. This results in producing a frictional force in proportion to the magnitude of the load being applied to the axial direction between the rollers 2 and the rotary member 1 nd between the rollers 2 and the passive member 3. At this time, since the rollers 2 slide while making rolling motions, sliding friction and rolling friction occur in combination to provide more stable resistance force.
