ABSTRACT:
A tire pressure detector without the risk of causing a leaky tire includes a base having a forward projected and externally threaded annular wall and an annular limit wall to define an annular groove therebetween; a mating cover having an internally threaded annular wall for screwing to the externally threaded annular wall of the base with a free end of the annular wall received in the annular groove to press against an airtight seal ring set in the annular groove, such that an airtight space is defined in and between the assembled cover and base; a tire pressure detecting assembly being receiving in the airtight space; and a valve control assembly being mounted on the base to locate between the base and the mating cover. The annular limit wall prevents the cover from moving and deforming at the screwed portion to ensure good air-tightness between the cover and the base.
