PROBLEM TO BE SOLVED: To provide a tire valve unit capable of preventing a sensor unit from separating from a tire valve.SOLUTION: A tire valve unit is formed by integrating a tire valve 20 with a sensor unit 40 which detects the inner state of a tire. The tire valve 20 includes a connection part 27 at the base end side, and the sensor unit 40 includes an insertion part 41 into which the connection part 27 is inserted. An engagement member 30 is provided on an outer peripheral surface of the connection part 27 so as to protrude and retract, and an engagement recessed part 43 with which the engagement member 30 is engaged is provided on an inner peripheral surface of the insertion part 41. The engagement between the engagement member 30 and the engagement recessed part 43 integrates the tire valve 20 with the sensor unit 40. |
