PROBLEM TO BE SOLVED: To provide a massage apparatus which improves a sensation of stretching around the pelvic bone. SOLUTION: The massage apparatus controls a pair of right and left airbags 20a and 20b arranged on a back rest 13 and a pair of right and left airbags 21a and 21b arranged on a seat 12 to operate together with a mutual time difference. By doing so, stretching, such as arching, twisting (pivoting and bending to the side) and bending forward and backward is carried out around the pelvic bone of a user. COPYRIGHT: (C)2010,JPO&INPIT
