Abstract
A power generator 1 includes a magnetostrictive rod 2 through which lines of magnetic force pass in an axial direction thereof, a beam portion 73 having a function of causing stress in the magnetostrictive rod 2, and a coil 3 provided so that the lines of magnetic force pass inside the coil 3 in an axial direction of the coil 3. A space between the magnetostrictive rod 2 and the beam portion 73 at the other end of the magnetostrictive rod 2 is smaller than that at one end of the magnetostrictive rod 2 in a side view of the power generator 1. In such a configuration, a stiffness in a displacement direction of a pair of opposed beams formed from the magnetostrictive rod 2 and the beam portion 73 becomes gradually lower from a proximal end thereof toward a distal end thereof. With such a configuration, when external force is applied to the distal end of the magnetostrictive rod 2, it is possible to smoothly displace the magnetostrictive rod 2 and the beam portion 73 in the displacement direction. Therefore, it is possible to make variability of stress caused in the thickness direction of the magnetostrictive rod 2 small. As a result, it is possible to cause uniform stress in the magnetostrictive rod 2 to thereby improve the power generating efficiency of the power generator 1.
