[Problem] To provide a hydraulic device for which there is no dead zone in the generation of force, and no contamination occurs. [Solution] To solve this problem, this hydraulic device as a solution for the present invention is equipped with a bottom cap 4 and a head cap 5 each of which is welded to an outer tube 3, and a rod guide 6 fastened to the head cap 5, with one end of a pipe 7 fitted into the bottom cap 4, and the other end of the pipe 7 fitted into the rod guide 6, and a cylinder 1 sandwiched between the bottom cap 4 and the rod guide 6. Accordingly, this hydraulic device is able to apply axial force to the cylinder 1 even while supporting, with the bottom cap 4 and the rod guide 6, the pipe 7 the interior of which is isolated from a tank T, and it is not necessary to solder the pipe 7 to the bottom cap 4. Therefore, with this hydraulic device there is no dead zone in the generation of force, and no contamination occurs. |
