[0039]

As described above, according to the first aspect of the present invention, since the massage member driving means is provided on the seat, the back is fixed at a desired angle with respect to the seat for use. In this case, even if a force that warps backward is applied to the back, the back together with the seat is unlikely to fall to the rear side, and the back and the seat are stable.

According to the second aspect of the present invention, since the massage member driving means is provided on the front end side of the seat, the seat and the back are more difficult to fall backward.
The back and seat are more stable. Further, by providing the massage member driving means at the front end side of the seat, the massage member driving means is provided at a position farthest from the user's ear, and noise generated from the massage member driving means is harsh. Is prevented.

According to the third aspect of the present invention, a pair of grooves extending in the front-rear direction and receiving the legs are formed in the seat, the front end faces of these grooves are opened, and a massage member is provided on the side surface of each groove. Since the massage member driving means is provided between the pair of grooves, the seat portion and the back portion are less likely to fall to the rear side, and the foot can be extended from the end surface of the seat portion. Massage of the legs can be performed regardless of the length of the legs, and the length of the seat can be shortened.

According to the fourth aspect of the present invention, of the components constituting the massaging member driving means, the bulky ones are arranged on the left and right sides of the seat, and the height of the central portion sandwiched between the left and right sides is adjusted to the left and right. Since the height is lower than the height, the center portion is easy to stretch the legs, and can be stretched even if you are tall without using the legs.

According to the fifth aspect of the present invention, the back has a headrest, and the back is foldable on the seat. When the back is folded on the seat, the headrest is Since it is accommodated in the central portion on the left and right sides, the thickness when the seat portion and the back portion are folded in two becomes thin, so that the seat portion and the back portion can be compactly stored.

According to the sixth aspect of the present invention, since the massage member is an air bag and the massage member driving means is an air supply means, the air bags provided on the seat and the back are lightweight, and the massage machine Is further concentrated on the seat provided with the air supply means as the massage member driving means. For this reason, the seat and the back are more difficult to fall backward, and the back and the seat are more stable.
