By fitting the table plate 35 from the front side, the table plate 35 is removably installed between the upper edges of the side plates 1, 1. In addition, 39, 39 are side plates 1,
After passing the fastening bands 40, 40 attached to the table board 35 through the band fittings 39, 39 with the band fittings attached to the back of the upper edge of 1,
The table board 35 is fastened to the chair body A by fastening the ends of the fastening bands 40, 40 with velvet fasteners or the like. In addition, the fastening position of the table board 35 can be adjusted forward or backward depending on the degree of hanging of the fastening band 40.

Reference numeral 41 designates a hip joint part used for preventing internal rotation and fixing the pelvis.A substantially L-shaped mounting rod 42 is attached to the lower surface, and this mounting rod 42 is mounted within a guide frame 43 attached to the front lower surface of the seat portion 2. By inserting and fastening with bolts 44, this hip joint part 41 is removably attached to the upper surface of the front end of the seat part 2. In addition, the guide frame 4 of the above-mentioned mounting rod 42
By adjusting the insertion width into the hip joint part 3, the attachment position of the hip joint part 41 can be adjusted back and forth. Next, reference numeral 45 denotes a head rest used to assist the neck in sitting, which has a neck support surface 46 curved in a concave shape on the front side, and a supporting arm 50 protruding from the back side. 47 so that the direction can be adjusted, and this mounting rod 4
