PURPOSE:To positively recover lost energy by arranging electromechanical energy converting piezoelectric element in a rubber tire, and thereby generating an electricity. CONSTITUTION:A plurality of rod-shaped or sheet-shaped piezoelectric elements 8, 9, 10, 11 are disposed in an automobile tire, a bicycle tire or other rubber tire. Since a deformation due to the own weight of the automobile which is losed energy when a tread 6 and sides 7 are largely rolled is generated from the tread and the sides, the elements 8, 9, 10, 11 are suitably mounted in the tread, in the sides or in the both. Thus, the energy loss due to the rolling of the rubber tire can be recovered by utilizing the piezoelectric phenomenon. |
