PROBLEM TO BE SOLVED : To provide an oscillating generator obtaining large power by improving a magnetic circuit structure of the oscillating generator and having an oscillating direction conversion mechanism for rotating an oscillating direction by 90 degrees.
SOLUTION : In the oscillating generator, R-Fe2 based supermagnetostrictive alloy element in which a mole ratio of one type or two or above types in Tb, Dy, Sm, Ho and Er of a lanthanide based rare earth element (R), and Fe is 1 : 2 and which includes Laves crystal structure is surrounded by a copper wire coil, oscillation is transmitted to the element and power is generated. (a1) Ferromagnetic magnets giving magnetic bias are arranged at both ends of the supermagnetostrictive alloy element, auxiliary yokes of a magnetic body performing a magnetization amplification operation are installed on external sides of the ferromagnetic magnets on both ends and a closed magnetic circuit is constituted. (b) Oscillation reception means are connected to the auxiliary yokes.
