PURPOSE: A device for boosting brake is provided to prevent the interference between the other part and a negative pressure connection pipe because rotating the negative pressure connection pipe by the external force is prevented and mounting angle of the negative pressure connection pipe joined to a brake booster is controlled. CONSTITUTION: A device for boosting brake comprises a cell(10), a negative pressure connection pipe(100), a sealing member, and a rotation prevention member(110). The cell comprises a static pressure chamber and a transformation chamber. The negative pressure connection pipe is connected to an external negative pressure source to maintain the pressure of the static pressure chamber under the atmospheric pressure. The rotation prevention member is installed between the negative pressure connecting pipe and the front side of the cell. The rotation prevention member prevents rotating the negative pressure connecting pipe or controls a mounting angle of the negative pressure connection pipe. |
