PROBLEM TO BE SOLVED: To provide an adjustment type tire air pressure sensor.SOLUTION: An adjustment type tire air pressure sensor attached to a wheel rim includes a sensor body 2, an air valve 3 and an air valve fixation part 4. The sensor body 2 includes a casing 21 and an air valve fitting hole 22, and the air valve fitting hole 22 has two limit contact surfaces parallel to each other and at least one linkage surface which links these two limit contact surfaces. The air valve 3 includes: two strained contact surfaces which respectively correspond to the limit contact surfaces and tightly contact the limit contact surfaces; at least one contact surface which is connected to the strained contact surfaces and the linkage surface; and a fitting hole directed to the air valve fitting hole 22. The air valve fixation part 4 is fitted into the fitting hole of the air valve 3 thereby fixing the air valve 3 to the sensor body 2. |
