Operating mechanism and assistive equipment

An operating mechanism is provided with an operating member (102A) which is pivotally supported by a first axis (121A), and a link member (103A) which is pivotally supported by a second axis (132A) and configured to transmit an operation of the operating member (102A) to a driving force transmitting member (111). A necessary load for an operation of the operating member (102A) is relieved at a ratio of distances between power working points and effort points, and support points in the operating member (102A) and the link member (103A).
