PURPOSE:To provide tilting with a wide angle by installing a pair of liquid pressure cylinders with a fluid pressure cylinder interposed, and by pivoting the piston rods of these liquid pressure cylinders at the two side faces of the fluid pressure cylinder each with a spherical bearing interposed. CONSTITUTION:Liquid pressure cylinders 21a, 21b are installed symmetrically with a fluid pressure cyliner 20 interposed, and the piston rods 26a, 26b of these liquid pressure cylinders 21a, 21b are pivoted at the two side faces of said fluid pressure cylinder 20 with spherical bearings 24a, 24b interposed, respectively, and then the protruding stroke pressure chambers 29a, 29b of the liquid pressure cylinders 21a, 21b are coupled with their return stroke pressure chambers 30a, 30 through liquid pressure circuits 31, 32. This provides tiltable installation of the fluid pressure cylinder 20 in any direction as well as its capability of tilting in a wide angle range within the mating plane regions of the two liquid pressure cylinders 21a, 21b, which will widen the scope of its applicability. |
