PURPOSE: A boot fixing device of a booster for a vehicle is provided to prevent a boot from being displaced, and to seal an opening end of a rear cell by modifying the installation structure of the boot covering the end of a valve body. CONSTITUTION: A boot fixing device of a booster in a vehicle is composed of an assembling part(12b) bent outward in an opening end(12a) of a rear cell; an assembling groove(91a) formed in the end of a boot(90) to combine with the assembling part; and a fixing end(91) contacted to the surface of a valve body(60). The boot protects the valve body by covering, and moves flexibly in operating the booster. The boot is prevented from being separated from the valve body with inserting the end of the boot to the opening end of the rear cell through the fixing end. The fixing end is combined with the assembling part, and contacted to the valve body with a sealing piece(91b). Assembling efficiency is improved, and the expenses are reduced without additional sealing members.
