Abstract: A cylinder is provided in which the length of a fluid supply pipe is reduced and the cylinder is installed in a fixed manner. The cylinder includes a main body that has an internal space and an upper supply aperture and a lower supply aperture through which fluid is supplied into the internal space. A piston is disposed between the upper supply aperture and the lower supply aperture to be vertically movable along the internal space. A rod is connected to the piston to transmit power produced by vertical movement of the piston to the exterior and a pipe extends from the upper supply aperture to a lower end of the main body.

Abstract: The present disclosure provides a pre-hemming apparatus including: an actuator which is coupled to one side of a main body; a pre-hemming body which is positioned at the other side of the main body and has a pre-hemming punch; and a driving link which connects the actuator with the pre-hemming body at the main body, has a plurality of link members that are operated by the actuator, and transmits force for pre-hemming a subject to the pre-hemming body when the plurality of link members are operated.
