Transmission device for transmitting information about tire condition and tire condition monitoring system
First Claim
1. A transmission device provided in a tire cavity area to transmit tire information about a condition of a tire, the transmission device comprising:
- a sensor configured to detect, as the tire information, a condition of gas filled in the tire cavity area surrounded with the tire and a rim;
a transmitter configured to wirelessly transmit the detected tire information;
a housing which houses the sensor and the transmitter, the housing including a wall that separates an inner space of the housing from the tire cavity area, the wall defining a through hole passing through the wall; and
an engaged member which is engaged with the through hole from an outside of the housing and is replaceable from the outside of the housing, the engaged member including one of an air vent and a communication groove configured to communicate between the tire cavity area and the inner space.

Abstract
A tire condition monitoring system includes a transmission device, a receiving device, and a monitoring section. The transmission device includes a sensor, a transmitter, a housing, and a engaged member. The sensor detects, as the tire information, a condition of gas filled in the tire cavity area surrounded with the tire and a rim. The transmitter wirelessly transmits the detected tire information. The housing houses the sensor and the transmitter, including an inner space and a through hole. The inner space is surrounded with a wall of the housing and is separated from the tire cavity area. The through hole passes through the wall. The engaged member is engaged with the through hole to be provided to the housing. The engaged member includes one of an air vent and a communication groove for communicating between the tire cavity area and the inner space.
