Abstract

A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting at least one of the gripping pieces; a pulley rotatably supported about a rotation axis parallel to the pivot axis; a wire wound around the pulley, causing tensile forces that move the rotation axis in one direction to act, and transmitting a pressing force; and a force-receiving portion receiving the pressing force. The pulley is disposed so that a resultant force of the tensile forces of the wire acting on the rotation axis generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be closed. The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.
