PIEZOELECTRIC ACTUATOR, AND TIMEPIECE AND PORTABLE UNIT WITH PIEZOELECTRIC ACTUATOR |
摘要 |
A diaphragm 10 is fixed to a base plate 102 by a screw 13. A lever 20 has a spring member 23, a rotor-fixing member 25, and an insertion hole 22 formed therein. By passing a shaft 21 through the insertion hole 22, the lever 20 is turnably supported so as to turn about its own axis. In a state in which the spring member 23 abuts against an eccentric pressure-adjusting cam 26, a pressing force for urging the diaphragm 10 via the rotor 100 is adjusted by turning the pressure-adjusting cam 26 so as to change an elastic force of the spring member 23. <IMAGE> |
