<P>PROBLEM TO BE SOLVED: To effectively generate power by using telescopic operation of a buffer, which includes a power generating set. <P>SOLUTION: The power generating sets 20A and 20B include a fixing member 40 which is fixed to the buffer 100, a movable member 41 which vibrates according to the elongation and contraction performance of the buffer 100 which is disposed oppositely to the fixing member and a spring body 42 which elongates and contracts according to the vibration of the movable member 41 to support the movable member 41. One of the fixing member 40 and the movable member 41 has an electret material 21 to which electric charge is applied. The other of the fixing member 40 and the movable member 41 has a counter electrode 22 which is disposed oppositely to the electret material 21. A plurality of the electret materials 21 and the counter electrodes 22 are disposed at a predetermined interval in the elongation and contraction direction of the buffer 100. Power is generated by electric differential generated between the electret material 21 and the counter electrode 22 corresponding to the vibration of the movable member 41. <P>COPYRIGHT: (C)2013,JPO&INPIT |
