PURPOSE: A tire pressure monitoring device is provided to be composed to replace a pneumatic sensing module separately without the replacement of an air injection valve on a tire. CONSTITUTION: A tire pressure monitoring device comprises a pneumatic sensing module(1) and a connection unit(10). The pneumatic sensing module senses the pneumatic pressure in a tire(T) and is installed an air injection valve(7) on a tire. The connection unit is composed of a connection nut(12) and a male thread portion(14) and connects the pneumatic pressure sensing module to the air injection valve to be detached. The connection nut is installed in the casing(1a) of a pneumatic sensing module into a single body. The male thread portion is formed on the exterior of the air injection valve.
