  • a circuit portion that detects pressure of the tire and generates a transmission signal that contains data representing the detected pressure of the tire; and

    a casing that accommodates the circuit portion, wherein the casing has a first pressure transmitting portion that transmits the pressure in the tire to the circuit portion so that the circuit portion can detect the pressure in the tire, wherein the pressure transmitted to the circuit portion through the first pressure transmitting portion produces force that presses the circuit portion, and wherein the casing further has a second pressure transmitting portion that transmits the pressure in the tire to the circuit portion to apply force that acts against the pressing force to the circuit portion.
