To make an air massaging apparatus possible to perform an effective massaging without the concentration of force on a part of a human body by providing air bags at a contact part in contact with the back of a user's body and arranging the bags along ribs of the body.

In the body 10 of a cushion as support body covered with a cover 11, rectangular air bags 12a-12g and 13a-13g, one to one paired between right and left groups, are arranged between an upper layer part and a lower layer part being horizontally divided almost at the center of the body 10 of the cushion and mounted inside the body 10 of the cushion in a figure of. A slight space as clearance is given between the ends of the air bags 12a-12g and 13a-13g at the center of the body of the cushion. When a user lies on the body 10 of the cushion with his back bone along the clearance, the length of the air bags 12a-12g and 13a-13g arrayed in the figure of is parallel along the length of the ribs. Then, a connection part 14 communicating with the air bags 12a-12g and 13a-13g is connected to a connection part 22 of an airing device 20 through a connection hose 23.
