A tire pressure gauge includes a housing, a tire pressure detection unit, an air valve, and at least two limit members. The housing has a lateral side and a chamber. The tire pressure detection unit is mounted in the chamber. The air valve is mounted to the housing, extending out of the chamber from the lateral side of the housing. The at least two limit members are mounted to the lateral side of the housing and located bilaterally at the air valve, each having an end surface to which the air valve is perpendicular. Accordingly, when the tire passes through the rough roadbed to be violently shocked or impacted, the tire pressure gauge of the present invention remains in original position because of positioning efficacy of the two limit members.
