description A pressure detecting indicator includes a cylinder, a seal ring and a valve driving part. The cylinder is sleeved with a tectum which has a transparent middle part, the valve driving part with an intake via is connected in the cylinder by a thread, an elastic membrane is provided between the valve driving part and the tectum, a pressure indication tube is provided on the elastic membrane, a spring is provided between the pressure indication tube and the tectum. The surfaces of the elastic membrane and the pressure indication tube both have patterns or color which indicates the pressure change, an indicative line is provided at the lower edge of the opaque part of the tectum; a graduation line is provided on the surface of the pressure indication tube. The utility model has simple structure, low manufacturing cost and convenient usage, by which the pressure changes of the pressure device and the pneumatic device can be indicated visually, the utility model is particularly applicable for the detection indication of the automobile tire pressure.
