The present invention relates to a device for preventing the eccentric pressurization of a pressure increasing vise capable of preventing eccentric pressurization from being generated in a slider for pressurizing workpieces to be fixed. A housing cover (130) for receiving a screw housing (109) to be rotated is arranged on a body (100). Stepped protrusions (141, 151) are formed on the outer diameter of the screw housing (109) and the inner diameter of the housing cover (130) through expansion parts (140, 150) to face each other. A belleville spring for applying elasticity to the screw housing (109) is formed between the stepped protrusions (141, 151). |
