A sensor apparatus ( 2 ) includes an acceleration sensor ( 11 ) provided in a vehicle body side raceway member ( 3 ) and detecting a lateral G, and a processing means ( 31 ) for computing a load by using an output of the acceleration sensor ( 11 ). The processing means ( 31 ) determines a lateral load Fy, a vertical load Fz, and a moment Mx caused by the lateral load on the basis of an output G of the acceleration sensor ( 11 ) in accordance with the following expression: <?in-line-formulae description="In-line Formulae" end="lead"?>Fy=Mx/a, <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Fz=bxG+c, and <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Mx=dxG<SUP>2</SUP>+exG+f, <?in-line-formulae description="In-line Formulae" end="tail"?> where a, b, c, d, e, and f respectively denote constants unique to a load detection target that is provided with the sensor apparatus.
