Abstract
A pointer gauge surface structure with an indication mark. A mark member is coupled on the surface of a pressure gauge or a micro-differential pressure gauge to display a critical value for a person to read with ease. A circumferential portion of a transparent casing is provided with a slide rail for engagement and slide of the mark member. The mark member has a C-shaped cross-section to provide a tightening function relative to the slide rail.
