Beschreibung
Zusammenfassung:	The present invention provides a lever-type frictional resistance force variable system comprising an arm whose upper end is rotatably supported by an upper beam; a supporting member which is fixed to a lower beam to rotatably support the intermediate portion of the arm; a braking device having frictional resistance plates connected to the lower end side of the arm, frictional pads provided between the frictional resistance plates, a pressing pad, and a screw rod; a turning lever connected to the screw rod; a ball screw threadedly engaging with the turning lever; a servomotor for rotating the ball screw; a displacement sensor for detecting a displacement of a frame; and a control unit for determining a braking force to be generated by the braking device based on the detected value of the displacement sensor and outputting a control signal according to the determined braking force.
