Abstract
A pressure gauge having pressure range indicating needles allows the positions of the pressure range indicating needles to be moved without detaching the cover from the pressure gauge body. The pressure gauge has an internal device, a pointer, a pressure scale plate and pressure range indicating needles, which are provided in the pressure gauge body. A window hole is formed in the cover. A transparent cover plate is fitted in the window hole of the cover in such a manner as to be capable of being opened and closed. With the cover left attached to the pressure gauge body, the tip of a screwdriver or the like can be brought into contact with the pressure range indicating needles through the window hole when the transparent cover plate is open, to move the pressure range indicating needles.
