ABSTRACT:
A vacuum brake power booster (1) has an electric travel sensor (3) for monitoring the position of a movable wall (4) furnishing the boosting power of the brake power booster. The travel sensor (3) is mounted by a sensor receptacle (2) which is made of plastic material and which is sealed off with respect to the booster housing (10) by means of a seal. In order to assure effective sealing by creating a constant degree of compression of the seal (7) despite different material thicknesses of the booster housing (10), angled tabs (12) are formed against which locking projections (11) are abutted.
