Claims

[Scope of claim for utility model registration] A tire pressure introduction part that is connected to the tire's gas supply hole and introduces the gas inside the tire, and an exhaust hole that opens and closes the tire pressure introduction part that exhausts the gas inside the tire that is input from the tire pressure introduction part. A pressure reducing means for reducing the tire pressure inside the tire, a tire pressure detecting means for detecting the tire pressure inside the tire using the gas inside the tire introduced from the tire pressure introduction part, and inputting the target value of the tire pressure as the adjustment target. a display means for displaying the tire pressure detected by the tire pressure detection means and the tire pressure input from the tire pressure input means; and a display means for displaying the tire pressure detected by the tire pressure detection means and the tire pressure input from the tire pressure input means. a control means for comparing the determined target value and controlling the pressure reduction means; detecting and displaying the tire pressure;
A tire pressure gauge that adjusts tire pressure to a target value input from a tire pressure input means.
