The present invention relates to a pressing device to carry out a work by fixing an object such as a tire. More specifically, the present invention relates to a functional hydraulic pressing device which uses hydraulic pressure, is easily manufactured, and can be easily separated or coupled even when being repaired afterwards. The present invention provides a hydraulic pressing device including a main body (100); a pressing unit (200); and a rod cover (300). Also, the present invention provides the hydraulic pressing device, in which the main body (100) includes a cylindrical space (110) and a casing unit (120); the pressing unit (200) includes a piston (210) and a rod (220); and the rod cover (300) includes a rod moving hole (310) and a cover unit (320). In addition, the present invention provides the hydraulic pressing device in which a male screw thread (331) is formed in a main body supporting unit of the rod cover and a female screw thread (212) is formed inside the casing of the main body, so that the main body and the rod cover are in a screw-fastened coupling structure. Also, the present invention provides the hydraulic pressing device in which a cover bolt hole (360) is formed at the cover unit of the rod cover and a main body bolt hole (140) is formed at an upper portion (portion where the cover unit of the rod cover comes into contact) of the main body, so that the main body and the rod cover are in a bolt coupling structure. |
