Abstract
An acceleration sensor includes a body supporting a casing within which a magnetic member is received. A plurality of magnets are mounted on the body and disposed around the casing. The magnetic forces of the magnets hold the magnetic member in a reference position within the casing. The magnetic member is displaceable from the reference position against the magnetic forces of the magnets when the acceleration sensor is subjected to acceleration. A detection device is mounted externally of the casing so as to detect displacement of the magnetic member from the reference position. The acceleration sensor further includes a position adjusting device for adjusting the position of at least one of the magnets relative to the casing so as to set the intensities of the magnetic fields of the magnets in predetermined relation within the casing.
