Abstract
A pendulum arm type high sensitivity self-aligning weighting arm includes a press assembly for pressing a driven body consisting of a roller body against a driving body such as a roller body or a belt body, wherein one end of the press assembly which has the function of holding and pressing the driven body and which provides a fulcrum for the weighting arm is supported in such a manner as to be capable of executing three motions, pitching, yawing and rolling, that is, it is supported in a pivot fashion, while the other end holds a rotatable roll shaft on the driven body side. The weighting arm is characterized in that a rolling-contact bearing element is interposed in a region of contact between the press assembly using a compression spring, compressed air or other fluid pressure for pressing the weighting arm, and the weighting arm through a cap.
