Abstract
Provide is a shutter which, even if the lift by which a gate is raised and lowered is long, reduces cylinder stroke to or below the lift and does not require the buckling strength of a cylinder to be increased. According to the invention, a cylinder is installed on a gatepost slab at the top of supports on both sides of a gate driven to rise and fall, and a pinion- mounting intermediate frame is installed at the bottom of the cylinder rod of the cylinder. Pinions are freely rotatably provided on both sides of the pinion-mounting intermediate frame, fixed racks that mesh with either the outsides or insides of the pinions are installed in vertical positions, and movable rack bars that mesh with the outsides or insides of the pinions are secured to the gate at their lower ends. Since the gate is driven by means of the movable rack bars meshing with the pinions raised and lowered by the same stroke as the cylinder rod which is driven by the cylinder to rise and fall, a cylinder stroke that is one-half or less the lift of the gate is sufficient.
