PROBLEM TO BE SOLVED: To suppress displacement of a treatment position with respect to an arm by enabling an arm treatment part to sufficiently follow movements of the arm in backward tilting movements of a backrest.SOLUTION: In a massage chair 11 including a seat part where a user can sit, a backrest part which can make backward tilting movements, and arm treatment parts on both right and left sides for performing treatment on arms, a seat rail part 25 for supporting a seat frame 31, being a framework of the seat part, in such a manner to move back and forth, and an arm rail part 26 for supporting an arm support body 61, being a framework of the arm treatment part, in such a manner to move back and forth, are provided on upper end parts on both right and left sides of a base frame 21. A back frame 41 being a framework of the backrest part is connected to the seat frame 31, and the seat frame 31 is supported to be movable to the front in association with backward tilting movements of the back frame 41. An interlocking mechanism 64 which converts forward movements of the seat frame 31 into backward movements of the arm support body 61 when the seat frame 31 moves forward is provided between the seat frame 31 and the arm support body 61. |
