PROBLEM TO BE SOLVED: To provide a massage chair capable of effectively improving the durability of a backrest part having a built-in massaging mechanism with a treatment device.SOLUTION: The inner cover member 33 and the outer cover member 34 disposed to close an opening of a back board are the parts on which a massaging ball 41a of the treatment device 41 works. The friction resistance in the cross direction in which the massaging ball 41a does not rotate is smaller than that in the vertical direction in which the massaging ball 41a rotates in the inner cover member 33 and the outer cover member 34.COPYRIGHT: (C)2009,JPO&INPIT【課題】施療子を有するマッサージ機構が内蔵された背もたれ部のカバーの耐久性を好適に向上することができるマッサージ椅子を提供する。【解決手段】バックボードの開口部を塞ぐように設けられた内側カバー部材33及び外側カバー部材34は、施療子41のもみ玉41aが作用する部位であり、この内側カバー部材33及び外側カバー部材34のもみ玉41aの回転しない幅方向の摩擦抵抗がもみ玉41aの回転する上下方向の摩擦抵抗よりも小さくなるように構成されている。【選択図】図4
