Air pressure detecting device for wheel
First Claim
1. An air pressure detecting device for detecting air pressure of a wheel of a vehicle which has a tire tube disposed in a tire, the air pressure detecting device being disposed between the tire tube and a rim of the wheel for detecting the air pressure of the tire tube comprising:
- an annular seat fixed against said tire tube and mounted adjacent to an opening defined in said tire tube;
a lid member held in removably fitting engagement with the seat;
a detecting and transmitting unit integrally mounted in the lid member for detecting air pressure in said tire tube and transmitting pressure information out of the detecting and transmitting unit.

Abstract
An air pressure detecting device for detecting the air pressure of a wheel of a vehicle which has a tire tube disposed in a tire. The air pressure detecting device is disposed between the tire tube and the rim of the wheel portion for detecting the air pressure of the tire. The air pressure detecting device includes an annular seat mounted in an opening defined in the tire tube. A lid member is removably fitted over the seat. A detecting and transmitting unit is integrally mounted in the lid member for detecting an air pressure in the tire tube and transmitting pressure information out of the detecting and transmitting unit. When the tire is to be replaced, the lid member is removed, and the detecting and transmitting unit is attached to a new tire for use.

9. An air pressure detecting device for detecting air pressure of a wheel of a vehicle during operation of the vehicle, the air pressure detecting device being disposed on a surface of a rim facing a tire and in a position between a tire tube and the rim for detecting the air pressure of the tire tube comprising:
-
an annular seat secured against an opening in said tire tube;
a lid member mounted on said seat; and
a detecting and transmitting unit secured to the lid member so as to be positioned in the opening of the tire tube and facing an inside of the tire tube, the detecting and transmitting unit for detecting air pressure in said tire tube and transmitting pressure information out of the detecting and transmitting unit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
