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, and a rectangular frame is attached onto the load sensor. A rod of the load sensor penetrates a web of the rectangular frame, a washer and a spring holder, and a coil spring is wound around the rod. A bush is fitted to an edge of a hole of the washer, and a step is formed between an upper surface of the washer and the bush. A nut is screwed to the rod and tightens a bottom of a cup portion of the spring holder. 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.
