Abstract
A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting the gripping pieces in a pivotable manner; a pulling pulley rotatably supported about a rotation axis parallel to the pivot axis; and a wire wound around the pulley, and causing, with a pulling force, the pulley to move the rotation axis. The pulley is disposed so that a resultant force of tensile forces of the wire becomes greater than the pulling force and generates a moment causing the gripping pieces to be pivoted relative to each other in closing direction. The base includes a first hole. At least one of the gripping pieces includes a second hole inclined in one direction with respect to the longitudinal axis of the first hole. The rotation axis is provided so as to be movable along the longitudinal axes of the individual holes.
