A constant pressure chamber and a variable pressure chamber are formed into sections, a passage is formed in the valve body and communicates the valve mechanism and the constant pressure chamber, an electromagnetic on-off valve is attached to the valve body and opens and closes the passage, and a passage is formed in the shell. In a brake booster equipped with an opening through which a harness connected to the electromagnetic on-off valve is inserted, and a sealing means for maintaining airtightness between the opening and the harness, large diameter pipes are telescopically fitted to each other. and a small-diameter pipe are arranged in the axial direction of the shell, one of the large-diameter pipe and the small-diameter pipe is connected to the valve body, the other is connected to the shell, and the harness is connected to the electromagnetic on-off valve. A harness guide device for a brake booster, characterized in that the brake booster is led out of the shell via both pipes and sealing means.
