In a seat with a movable armrest, a support shaft is installed in one side plate of the seatback frame that can be raised and lowered, and extends horizontally outward from the seat, and has a screw hole at its tip, and a support shaft is installed at a suitable location on the outer circumference of this support shaft. The support shaft is fitted into the implanted support piece and the pivot hole drilled in the rear end side wall so as to be rotatable;
An armrest frame has an opening in the lower surface of its tapered front end and a locking piece cut and raised in the middle of the side wall; An extending connecting rod, a large-diameter coil spring interposed at the base end of the connecting rod, one end of which contacts the locking piece, and the other end of which contacts the collar of the connecting rod to urge the connecting rod toward the proximal end; A through-hole is bored in the appropriate position of the hook-shaped upright piece, and an operating piece is made to face from the opening,
It consists of an operating handle member pivoted near the opening, and a coil spring disposed inside the front end of the armrest frame to bias the operating piece downward, and the free end of the connecting rod is inserted into the through hole of the upright piece. A steplessly adjustable armrest for a seat is characterized in that the armrest is engaged with and disengaged from the sharp edge of the through hole.
