摘要：
A configuration is adopted where elastic members made of expanded rein beads and having a size covering air cushions are disposed between a skin member and the air cushions of a human body supporting device. By arranging a plurality of elastic members made of expanded rein beads and in a stacking manner, preferably, arranging two elastic members made of expanded resin beads, spring constants of the elastic members obtained from load-deflection characteristics when they are pressed to a deflection amount of 1 mm by a pressing plate with a diameter of 30 mm being higher than that of the air cushion and being different from each other, a biological signal can be transmitted to the air cushions without damping the biological signal, though the elastic members made of expanded rein beads and are provided.
