PROBLEM TO BE SOLVED: To provide a power generator capable of generating power with a generated power amount having small variation while giving excellent operational feeling.SOLUTION: A power generator 1 comprises: a frame 2; a long power generation element 10A which is installed in the frame 2 and comprises a magneto-striction bar and a coil installed on the outer peripheral side of the magneto-striction bar so that voltage is generated depending on expansion and contraction of the magneto-striction bar; an axis 3 for rotatably supporting the power generation element 10A to the frame 2; an operation part 4 for performing rotation operation of the power generation element 10A with respect to the frame 2; an energy storage part 5 for storing at least one of elastic energy and magnetic energy to be converted to kinetic energy required for rotation movement of the power generation element 10A; and a restriction part 6 for restricting the rotation movement of the power generation element 10A with respect to the frame 2. |
