Abstract: In a toggle-type mold-clamping apparatus including at least a pair of swingable arms and toggle pins for connecting the arms in a swingable manner through toggle bushings each of which is constructed of a cylinder element and pellets embedded in a peripheral surface of the cylinder element at intervals of a certain distance so as to be exposed to an inner peripheral surface of the cylinder element, while a lubricant film of a grease mixed with fine particles of solid lubricant is applied to sliding surfaces of the toggle pins and the toggle bushings, resulting in excellent lubrication being realized in the apparatus.
