設けたことを特徴とする運転用座席装置。 In a driver's seat provided on the upper surface of a support base via a seat elevating mechanism, a front bracket is erected at the front of the upper surface of the support base, and the lower front end of the elevating mechanism is rotatably attached to the front bracket. It is pivoted by a pivot pin, and brackets with elongated holes are erected at the rear of both sides of the elevating mechanism, and the longitudinal center line of the elongated holes of the bracket is set from the pivot pin of the front bracket. A plurality of stepped locking parts are provided at equal distances and on the inner surface in the longitudinal direction of the elongated hole, and a through pin is provided that penetrates the elongated hole and the rear end of the lower part of the lifting mechanism. A narrow width portion is provided at each end of the pin at the insertion position of the elongated hole of the bracket, and the width of the narrow portion is set to be smaller than the interval between the stepped locking portions of the elongated hole. A handle is fixedly provided near the center of the through pin, and when the seat and the rear side of the elevating mechanism are rotated upward, the handle is rotated so that the narrow part of the through pin becomes a stepped elongated hole. When the locking portion is enabled to pass through and the seat and the elevating mechanism are locked at a required rotation angle, the handle is configured to be able to rotate and lock onto the outer diameter portion of the through pin, and A driver's seat device characterized by having a clamp bolt mechanism capable of tightening and fixing both ends and a bracket with an elongated hole.
