FIELD: motor vehicle industry.
SUBSTANCE: device contains elements reacting on air pressure decreasing, and alarm block. Element reacting on the air pressure decreasing is the indicating wheel linked by the follower with the converter of the mechanical movements to the electrical signals entering the electronic alarm block. The indicating wheel coming in contact with the pavement during pressure decreasing in the vehicle tyre is made with diameter equal to height of the tyre section, and is located such, that its bottom mark is above the pavement by 0.5 of tyre section height.
EFFECT: increased safety due to timely driver warning about the tyre pressure decreasing.
