TRANSMISSION DEVICE FOR TRANSMITTING INFORMATION ON TIRE STATE, AND TIRE STATE MONITORING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transmission device and a system capable of appropriately measuring and acquiring tire information such as tire air pressure information even if the puncture of the tire is repaired using a puncture repair agent in a new method different from a conventional method. SOLUTION: The transmission device includes: a sensor which detects the state of gas filled in a tire cavity area as tire information; a transmitter which wirelessly transmits the detected tire information; and a housing which houses the sensor and the transmitter is provided an inner space partitioned from the tire cavity area by a wall, and has a through-hole for penetrating the wall; and a locking member locked with the through-hole and mounted to the housing. The locking member has a communicating hole and a communicating groove for making the tire cavity area communicate with the inner space. COPYRIGHT: (C)2011,JPO&INPIT
