POWER GENERATING ELEMENT

摘要

A power generating element includes two pillar-shaped magnetostrictive bodies through which lines of magnetic force pass in an axial direction thereof, each of the two pillar-shaped magnetostrictive bodies formed of a magnetostrictive material; a pressing body having a pressing part provided so as to press the magnetostrictive body when the pressing part is pivotally moved and a rod part for pivotally moving the pressing part; and a coil provided so that the lines of magnetic force pass through in an axial direction thereof and in which a voltage is generated on the basis of a variation of density of the lines of magnetic force. The power generating element is configured to vary the density of the lines of magnetic force when the pressing part is pivotally moved due to a pivotal movement of the rod part around a pivotal center and then the magnetostrictive body is pressed and compressed by the pressing part.
