To provide a power generator for lessening restriction concerning kinds, measuring intervals or the like of sensors used by a tire air pressure monitoring device by driving the tire air pressure monitoring device without using components required periodically for exchange.
The power generator has an outer wall 2 forming an air chamber 5 in the inside and a power generation plate 3 provided on the outer wall 2 and allowing one face to face the air chamber 5 and the other face to face an outside space. The power generator 1 is composed so as to generate power by generating an air pressure difference between the air chamber 5 and the outside space by air pressure variation of the outside space to generate shape change on the power generation plate 3.
