Abstract
A pressure gauge has an indicator needle and a scale plate. A preset pressure indicating member extending along a pressure scale in a circular arc pattern is slidably attached to a front wall of a case, and provided with a first display section. An opaque shield portion provided with a second display section at one end thereof is provided to a transparent cover rotatably attached to the front wall. The transparent cover drives the preset pressure indicating member to set a preset pressure range between the first display section and the second display section which is observable from the outside through the transparent cover.
