Abstract
A pressure sensor has a diaphragm that is exposed to air in a tire of a vehicle. A transmitter wirelessly transmits data representing the air pressure of the tire. A casing accommodates the transmitter and the pressure sensor. A lid closes an opening of the casing. A metal body is provided on the lid. When the opening of the casing is closed with the lid, the diaphragm is covered with the metal body.
