PROBLEM TO BE SOLVED: To provide a technique for facilitating changing of the spring constant of a leaf spring interposed between a coil and a permanent magnet.SOLUTION: An intermediate vibration body 4 of a vibration-based generator 1 includes a coil 31, a magnet 22 (a permanent magnet), and an inside elastic connector F (an elastic connector) which elastically connects the coil 31 and magnet 22 to each other so that the coil 31 moves reciprocally and relatively to the magnet 22. The inside elastic connector F is constituted by combining two leaf springs 34 having different spring constants with each other. The plurality of leaf springs 34 include a leaf spring 34P for rough adjustment which roughly adjusts the spring constant of the inside elastic connector F, and a leaf spring 34Q for fine adjustment which has a smaller spring constant than the leaf spring 34P for rough adjustment to finely adjust the spring constant of the inside elastic connector F. |
