Title:
AIR PRESSURE SENSING DEVICE FOR TIRE
Document Type and Number:
Japanese Patent JP2005153722
Kind Code:
A
Abstract:
To provide an air pressure sensing device for a tire capable of specifying certainly a tire whose air pressure has dropped using a simple constitution.
The air pressure sensing device for the tire includes sensors 12 mounted on a plurality of tires 1a-1d to be fixed to a vehicle for sensing various sorts of measuring data containing the tire air pressure, transmitters 2a-2d to transmit the measuring data sensed by the sensors 12, and a receiver 4 to receive the measuring data transmitted from the transmitters 2a-2d, wherein the transmitters 2a-2d mounted on the tires 1a-1d transmit the measuring data in a plurality of times at different intervals with the predetermined cyclic period.
