PROBLEM TO BE SOLVED: To provide a massage machine capable of simplifying the structure.SOLUTION: A massage machine includes an air supply source, a plurality of air actuators including at least one air actuator as an operation part for massage, and a switch valve 12 for switching and supplying the air from the air supply source to any actuators among the plurality of air actuators. The switching valve 12 has a body 20, a valve body 21 mounted for sliding and rotating in the body 20 and freely moving between the air supplying position for supplying the air from the air supply source to the air actuator and the air discharge position for discharging the air supplied to the air actuator outside the body 20, and a driving mechanism for switching the air actuator where the differential pressure between the inside pressure and the outside pressure of the body 20 is used and the air supplying position and the air discharge position are switched by sliding the valve body 21, and the valve body 21 is rotated and communicated to the air supply.COPYRIGHT: (C)2011,JPO&INPIT【課題】構成の簡素化が図れるマッサージ機を提供する。【解決手段】エア供給源と、少なくとも1つがマッサージ用の動作部である複数のエアアクチュエータと、前記複数のエアアクチュエータの内のいずれかへ前記エア供給源からのエアを切換えて供給する切換弁12とを有するマッサージ機である。前記切換弁12は、本体部20と、前記本体部20内に摺動及び回動可能に設けられ、前記エア供給源からのエアを前記エアアクチュエータへ供給させる給気位置と、前記エアアクチュエータへ供給されたエアを前記本体部20外へ排気させる排気位置との間を移動自在の弁体21と、前記本体20部の内部圧力と外部圧力との差圧を利用して、前記弁体21を摺動させて前記給気位置と前記排気位置とに切換え、且つ、前記弁体21を回動させて前記エア供給源と連通させる前記エアアクチュエータを切換える駆動機構と、を有している。【選択図】図3
