<P>PROBLEM TO BE SOLVED: To provide an opening/closing device from which electric power is allowed to be obtained with ease. <P>SOLUTION: The opening/closing device according to the present invention comprises an opening/closing body (a shutter curtain 4) for opening/closing an opening part 13 and a storage part (a case 2) for storing the opening/closing body in a state where the opening part is opened. In the opening/closing device where another end stops in an engaged state to an outside surface of the storage part with the opening part being opened and the other end lands to thereby close the opening part, the opening/closing body comprises a piezoelectric element (an opening/closing body side piezoelectric element 31, a case side piezoelectric element 32) provided so that pressure is applied to at least one of the other end (a bottom surface of a creasing parallel portion 28) or the outside surface of the storage part (a bottom surface of guide means 27) by the opening/closing body being opened/closed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
