    • PROBLEM TO BE SOLVED: To provide an air-pressure measuring apparatus, for a tire, by which the actual air pressure of the tire in a bicycle or the like can be measured with good accuracy and easily. SOLUTION: This air pressure measuring apparatus is provided with a base part 2 in which an opening part 7 is bored and formed, In addition, it is provided with holding members 3 which are fixed to the base part 2 and which are attached to a tire. In addition, it is provided with a fixed grip 14 which is erected and installed on the surface of the base part 2. In addition, it is provided with a moving grip 19 which can be slid in the longitudinal direction on the surface of the base part 2. In addition, it is provided with a moving member 4 which is connected to the moving grip 19 via the opening part 7 in the base part 2. In addition, it is provided with a positioning means which is attached to the moving member 4 and by which the distance between the holding members 3 and the moving member 4 is set at a shortest distance. In addition, it is provided with a pressure detection means 5 which is attached to the moving member 4 and which detects the air pressure of the tire at a time when the distance between the holding members 3 and the moving member 4 becomes the shortest distance.
