摘要： A conventional solid protection device disposed on an exposed side of a cylinder for actuating a working device had a possibility of being permanently deformed by contacting an obstacle so as to be prevented from sliding properly corresponding to the telescopic movement of the hydraulic cylinder. An object of the invention is to provide a hardly deformable protection device. To protect an exposed side of a cylinder for a working device, a protection device 30 includes a guard member 32 and a slide guide 31 into which guard member 32 is telescopically fitted. Slide guide 31 is attached to a cylinder tube 9a, and a tip of guard member 32 is attached to a tip of piston rod 9b. Guard member 32 is a flat plate made of spring steel. A width of guard member 32 is larger than a diameter of the piston rod. Notches 32a are provided on lateral opposite sides of a basic side end of guard member 32. Sliders 33 are fitted to respective notches 32a. The top of guard member 32 is bent into a roll-shape so as to serve as a pivotal portion.

摘要： A protective device provided on the exposed side of a cylinder for driving a working machine has been constructed solid, and as a consequence, the device is permanently deformed when it is in contact with an obstacle, sometimes becoming unable to slide in conjunction with telescoping of the hydraulic cylinder. To solve such a problem, a protective device not easily deformed is provided. The protective device (30) for protecting the exposed side of a cylinder of a working machine has a guard member (32) and a slide guide (31) capable of receiving in a telescopic manner the guard member (32). Further, the slide guide (31) is installed on a cylinder tube (9a), and the head of the guard member (32) is installed on the head of the piston rod (9b). The guard member (32) is a flat plate of spring steel, and the width of the guard member (32) is set greater than the diameter of the piston rod. Cutouts (32a) are provided on both sides in the width direction of the base side end of the guard member (32), a slider (33) is fitted in the cutouts (32a), and the head of the guard member (32) is bent in a roll shape to form a pivot support section.
