PROBLEM TO BE SOLVED: To provide a massage machine, preventing deformation of a member when an impact is applied without any increase in size of the member to be reinforced. SOLUTION: This massage machine includes: a seat part; a backrest part turnably fixed to the seat part; and a connecting part 4 provided to turn the backrest part. The connecting part 4 is constructed so that the end part of an expanding and contracting actuator and a lower frame 14 of the backrest part are turnable. The connecting part 4 has a buffer means 13 for absorbing impact force applied between the end part of the expanding and contracting actuator and the lower frame 14. COPYRIGHT: (C)2007,JPO&INPIT
