PURPOSE: A booster for a vehicle is provided to adjust the shaft direction length outside by being formed between the divided plungers installed between an input shaft and an output shaft for adjusting the property of an output when the booster is assembled already. CONSTITUTION: A front plunger(181) and a rear plunger(185) are combined by a screw. The front plunger is fixed to rotate the rear plunger. Thus, the outer circumference of a front nut(182) of a front plunger(181) and a guiding hole(191) of a limit member(190) are in square shapes. Then the front plunger is freely moved in a shaft direction and inhibited from rotating. To adjust the property of an output, a filter unit(150) is extended outside and an adjusting bar(189) is inserted into a valve body(130) through an inlet hole(134). The adjusting bar is inserted into an adjusting groove(188) of the rear plunger and rotated with an input shaft(170). Thereby, a rear bolt unit(186) inside the front nut is rotated to adjust the shaft direction of a plunger(180) and to adjust an output gap(G) between the front plunger and a rebounding plate(141) at the same time.
