Abstract: A carrier module of a tire pressure monitoring device includes a plastic carrier and a metallic tube. The plastic carrier has a trough and a tube extended from a bottom portion of the trough. The trough has an airflow channel penetratingly formed on the bottom portion thereof, and the trough is in air communication with the tube by the airflow channel The metallic tube is seamlessly formed on an inner surface of the tube of the plastic carrier. The metallic tube has an inner screw thread formed on an inner surface thereof for detachably screwing to a nozzle of a tire. Thus, by seamlessly forming the metallic tube on the inner surface of the tube of the plastic carrier, the tire pressure monitoring device of the instant disclosure has a better airproof effect and a longer service life.
