Abstract
An upper rail is movable in a rear and front direction with respect to a lower rail fixed to a vehicle floor. A load sensor is fixed to an upper surface of the upper rail 4, and a rectangular frame 30 is attached onto the load sensor. A rod of the load Sensor sequentially penetrates a web of the rectangular frame, a plain washer and a spring holder upward, and a coil spring is wound around the rod. A bush is fitted to an edge of a hole of the plain washer, and a step difference is formed between an upper surface of the plain washer and the bush. A nut is screwed to the rod, and the nut tightens a bottom of a cup portion of the spring holder. In such a way, the coil spring is sandwiched between the spring holder and the web and is compressed, and an end portion of the coil spring engages with the step difference.
