PURPOSE:To make it efficient by controlling the electrodes excluding the ones for driving to a common electrode by means of a switch. CONSTITUTION:The oscillating body of an oscillating motor is constituted of an elastic body such as metal, etc. and a piezoelectric element stuck to this. And this piezoelectric element is equipped with A-B phase electrodes A1-A7 and B1-B7 for driving, the common electrode C, and an electrode S for sensor. Moreover, this has electrodes CD1-CD2 for adjustment of rigidity nonuniformity, and is put in short circuit condition with the common electrode C or release conditions with the first and second switches SW1-SW2. As a result, by the opening of the switches SW, the rigidity at the part can be elevated. |
