A pressure-sensing massage machine that resolves the problems of difficult assembly and adjustment and the occurrence of operational errors common to a sensing mechanism that uses many components and devices. The massage machine of the present invention is able to monitor the pressure applied to the massage recipient by a motor-driven movably extending massaging member. A flexible member is provided in the transmission located between the massage member and the motor that drives the massage member, and a pressure sensing mechanism monitors the pressure applied to the massage recipient through the flexible displacement of the flexible member.

In an energy recovery type surface acoustic wave motor, an increase in energy efficiency at the time of energy recovery and supply is achieved by adjusting phase change. A surface acoustic wave motor comprises: a surface acoustic wave substrate; a slider provided with an applied pressure; a driving interdigital electrode connected to an external power supply for generating a driving surface acoustic wave on a surface so as to drive the slider by a frictional force which is generated on a contact surface of the slider with the surface acoustic wave substrate based on the surface acoustic wave and the applied pressure; recovery interdigital electrodes placed forward and backward in the direction of travel of the surface acoustic wave for recovering energy of a surface acoustic wave unused to drive the slider, and for using that energy to generate a surface acoustic wave; and phase adjusting means for matching the phase of a surface acoustic wave generated by the recovery interdigital electrodes to the phase of the driving surface acoustic wave generated by the driving interdigital electrode.
