POWER GENERATOR, OPENING/CLOSING DETECTION DEVICE, AND RADIO SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power generator capable of easily regulating the power generation capacity of a power generation part.SOLUTION: The power generator includes the power generation part, a first moving member which slidingly moves relative to the power generation part to allow the power generation part to generate power, and a second moving member 41 which is constructed to slidingly move. When moving inside a predetermined movement section L, the second moving member 41 slidingly moves while engaging with one of the power generation part and the first moving member to make the power generation part and the first moving member slidingly move relative to each other. When moving outside the predetermined movement section L, the state of engaging with one of them is released not to make the power generation part and the first moving member slidingly move relative to each other.
