ABSTRACT:
An improved pressure reading structure for a pressure gage is disclosed, comprising a data plate, a rotable pointer and a protection casing. The data plate includes a central area and an extended area next to and connected to the central area, both of the areas being positioned on different planes to serve as an upper area and a lower area thereof respectively. In addition, the rotable pointer has a first end mounted above the central area of the data plate, a second end mounted above the extended area of the data plate, and a needle relative to the data plate to form a space. Accordingly, tire pressure can be read from different view angles, and also, use of the pressure gage becomes more convenient.
