Since it is pressed from the side, it is possible to perform a stretching operation that opens the chest left and right. And since the 1st air cell which presses a shoulder part from the front is located above a shoulder part, when sitting on a massage machine or when not massaging, a 1st press part will become obstructive. Can be prevented.

In this case, it is preferable that the 2nd press part is located in the left-right direction inner side rather than the 1st press part. Furthermore, before Symbol second pressing portion, the upper end and the base, it is preferably configured so as to expand toward the front from the rear of the lower end as the expansion unit. The second pressing portion may be configured to expand from the rear to the front with the laterally outer side as a base and the laterally inner side as an expanded portion.

Moreover, it is preferable that the said support part further has the 3rd press part which presses the shoulder part in a user's torso from upper direction, and the 4th press part which presses a user's neck part from right and left. In this case, it is preferable to have a control part which controls operation | movement of each said press part, and the said control part is comprised so that at least a 3rd press part and another press part may be controlled independently.
