PROBLEM TO BE SOLVED: To naturally and effectively perform the operations of lifting the pelvis and turning it around a body axis by the expansion and contraction of an air bag by a simple configuration in a chair type massage machine. SOLUTION: The massage machine 1 is a reclinable chair type massage apparatus provided with a backrest part 2 and a seat part 3 and is provided with the air bag 4 disposed to the backrest part 2 and the seat part 3 for pressurizing a human body by the expansion or the contraction, and the air bag 4 is formed integrally over both of the backrest part 2 and the seat part 3. Since the air bag 4 is formed integrally over both of the backrest part 2 and the seat part 3, pressurizing force by the expansion and contraction of the air bag 4 is made to act on the almost centroid of the pelvis of a user, the entire pelvis of the user is lifted and turned under a natural operation feeling, and muscles around the pelvis are relaxed.
