ジヤスタ。 It consists of a pair of lower rails extending on the floor and a pair of upper rails that are fitted to the lower rails so as to be slidable back and forth, and between the upper rails, the upper rails are rotatable on front and rear bearing members respectively attached to the front and rear of the upper rails. A pair of rods are provided that are pivotally supported by the lower rails, and the pair of rods are respectively engaged with threaded portions formed on a pair of fixing members attached to the pair of lower rails, and the rotary drive device is fixed to the one lower rail. A rotational force is applied to the rod of one of the upper rails, and the rotational force of this one rod is transmitted to the other rod via a belt provided between the pair of rods, and the rotational movement of the pair of rods causes A seat adjuster characterized in that the pair of upper rails are slid together.
