ABSTRACT:
An operating device of an opening-closing body is supported on both sides on a single rotating shaft and controls the turning torque of the rotating shaft. To realize the operating device, a rotating shaft having a flange portion on one side is rotatably mounted by inserting in a pair of bearing holes coaxially formed in a pair of bearing members which are erected as parallel walls at a predetermined spacing; the rotating shaft being provided with opening-closing body mounting portions on both ends which protrude out of the pair of bearing members; a friction washer is interposed between the flange portion and the bearing member and rotates together with the rotating shaft; a stationary cam member is secured on one of the bearing members, with the rotating shaft rotatably inserted through at the central part; a rotating-sliding cam member is disposed oppositely to the stationary cam member and capable of sliding in the axial direction of the rotating shaft while turning together with the rotating shaft; and furthermore a compression spring is inserted over the rotating shaft to press the rotating-sliding cam member towards the stationary cam member side to thereby press the friction washer between the flange portion and the bearing member. The compression spring can adjust a pressure to be applied to the rotating-sliding cam member and a pressure to be applied to the friction washer.
