PURPOSE:To detect inclination and acceleration on an analog basis in every direction by combining a signal generation source with >=3 receiving elements. CONSTITUTION:When a housing 1 is horizontal, Hall elements 13a-13c are at equal distance from a magnet 12, so the magnetic detection quantities of the Hall elements 13a-13c are equal. If, however, the housing tilts according to the motion of a vehicle, a float 8 in a hollow spherical body 4 holds itself in a perpendicular center 10 with a weight 1 all the time, so the analog values of the Hall elements 13a-13c vary with the distances to the magnet 12. The analog outputs 15a-15c of the respective Hall elements 13a-13c are inputted to a control unit 14 and passed through amplifiers 16a-16c and a relative computing element 17 takes an arithmetic analysis to obtain an inclination output (acceleration output) 18.
