Document Type and Number:
Japanese Patent JPS5710530
Kind Code:
B2
Abstract:
A casing is disposed in an air pressure chamber of a pneumatic tubeless tire and carries therein a switch cooperating with an alarm to produce an alarm signal upon a fall in the air pressure in the tire below a predetermined value. The switch is controlled by a leaf spring which is deformable by the movements, in one direction, of a flexible diaphragm deformable in response to variations in the air pressure in the tire. The leaf spring is returnable by its resilient force upon the movements, in another direction, of the diaphragm. The casing is fixedly mounted on a wheel rim through a projection extending outwardly of the tire from the casing through the rim.
