Abstract

PROBLEM TO BE SOLVED: To improve the attaching property and the installation property to a back frame by fixing an arm rest and an attaching bracket for the connection of an arm to a movable frame, which constitutes the tilting section of a back rest section, and forming the attaching bracket into a shape having a closed cross section. SOLUTION: The rear ends and the lower ends of a pair of right and left bracket pieces having an L-shape cross section are assembled to movable frames 30B and 30C in such a manner that an attaching bracket 2 may present the closed cross section shape, and are integrally welded. Then, at the upper side of the attaching bracket 2, a through hole, through which the spindle 10 of an arm rest 1 is passed, and an arc-shape slot, through which a stopper shaft 11 is passed, are provided. Also, at the lower side of one bracket piece constituting the attaching bracket 2, a slide hole 22 is provided. Then, an arm 4 is connected to the attaching bracket 2 by slidably fitting a connecting pin 41 in the slide hole 22. By this constitution, the attaching property and the installation property to a back frame 3 can be improved.
