ABSTRACT:
A vibration sensor for an automotive vehicle including a piezoelectric vibrator of cantilever type for detecting mechanical vibrations, such as knocking, from an engine body. The vibration sensor prevents the vibrator from being deformed by thermal stress even if temperature near the sensor rises sharply, so that a stable resonant frequency will be maintained when detecting the vibration of an engine body.
