The display device includes a message indicator for displaying the internal pressure of the tube as detected by the sensor. The message indicator has a plurality of alphanumeric display elements each consisting of a plurality of segments. The display elements are used to display a value, in alphanumeric terms, of the internal pressure of the tube. Further, some of the segments of the display elements are used to display the quantitative change of the pressure as a bar graph.
