Title:
TRANSMISSION DEVICE FOR TRANSMITTING INFORMATION RELATING TO CONDITION OF TIRE, TIRE ASSEMBLY, AND TIRE CONDITION MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/098858
Kind Code:
A1
Abstract:
A transmission device of a tire condition monitoring system comprises a sensor which detects, as tire information, the condition of gas filled into a tire cavity region, a transmitter which transmits the detected tire information by radio, and a housing which covers the sensor and the transmitter. An opening that connects an internal space within the housing and the tire cavity region is provided in the surface of the housing, and the opening is provided so as to extend on the surface of the housing while forming the shape of a straight line, a curved line, or a combination of a straight line and a curved line. The maximum value of the opening width orthogonal to the direction in which the opening extends is 0.8 mm or less. Even if a flat tire is fixed using a puncture sealant, tire information such as tire pressure information can be appropriately measured and acquired by this transmission device.
