PURPOSE: A cylinder is provided to simplify the structure thereof by simultaneously performing linear and rotary motions through the one-time actuation of a piston. CONSTITUTION: A cylinder (100) comprises an outer cylinder block (200), an inner cylinder block (300), a piston (400), a rotating part, and first and second covers (600, 610). One end of the outer cylinder block is open, and the other end is blocked. First and second vent holes (210, 211) are formed on both ends of the outer cylinder block. The inner cylinder block reciprocates between the first and second vent holes. The piston is installed on the inner side of the inner cylinder block to be rotated, and a rod (410) is formed on one end thereof. The rotating part rotates the piston when the cylinder is actuated. The first and second covers are coupled to the open ends of the outer and inner cylinder blocks and have through holes where the rod penetrates through. |
