PIEZOELECTRIC ACTUATOR MODULE, MOTOR MODULE, AND DEVICE

摘要

Disclosed is a piezoelectric actuator module which can be handled easily, made thin and offers high versatility. An actuator module (10) comprises a piezoelectric actuator main body (21) having an electrode, signal input terminals (18A-18D) to which driving signals are input from the outside for feeding the driving signals to the electrode, a rotary body (22) which is arranged on the substantially same plane as the piezoelectric actuator main body (21) and rotationally driven by the piezoelectric actuator main body (21), a case (15) for housing the rotary body (22) and the piezoelectric actuator main body (21) to which the signal input terminals are electrically connected, and an output shaft (12) which is exposed from the case (15) for outputting the rotational movement directly or indirectly transmitted from the rotary body (22) to the outside.
