ABSTRACT:
A headrest device of a chair in which a headrest can be stably supported by a headrest frame and the operation for mounting a vertically moving member of the headrest is easily performed. Guide grooves are formed in the side faces of guide rails at the front faces of the right and left side-rods of the headrest frame. The right and left guide rails are so held by a pair of right and left lifting brackets, which are provided on the rear surface of the headrest and are formed in rearward U-shape when viewed from above, as to be capable of sliding vertically from the front. Projected guide pieces formed to be projected on the inner surfaces of both vertically moving brackets and facing in the vertical direction are slidably fitted into the guide grooves of the right and left guide rails.
