<P>PROBLEM TO BE SOLVED: To provide a piezoelectric power generator hardly causing breakage of a piezoelectric element, and capable of obtaining sufficient power generation amount without causing scale-up of the device. <P>SOLUTION: The piezoelectric power generator 1 is configured so that a fixing member 5 is fixed on the internal circumferential surface of a tire 2 as a rotary body, a first end 6a as an end of a lengthwise direction of a piezoelectric element 6 is fixed on the fixing member 5, and a pressing member 7 is disposed outside the lengthwise direction of the piezoelectric element 6. In this power generator 1, when the internal circumferential surface of the tire 2 is deformed, an end of the pressing member 7 which is a side opposite to a piezoelectric element 6 side is moved to a rotary center side of the rotary body, and a second end 6b of the piezoelectric element 6 of the pressing member 7 causes the pressing member 7 to press the piezoelectric element 6 in a lengthwise direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
