Summary:A vibration sensor having a pressure sleeve in which the pressure sleeve may be mounted under pressure on a component causing vibration. To detect a vibration signal, e.g., in the case of a knock sensor, a sensory system is held by a seismic mass above it on the outside of the pressure sleeve via a screw connection on a contact face of the pressure sleeve under an axial prestress in the direction of the sensory system. The seismic mass has an inside thread and may be screwed onto the sensory system to produce the axial prestress in the direction of the sensory system. A seismic mass or the sensory system has at least two opposing grooves running radially opposite one another, so that the plastic may enter an interior space between the sensory system and the pressure sleeve during extrusion through these grooves.
