PROBLEM TO BE SOLVED: To provide a vehicle state monitoring device for detecting the state of a grounding section of a tire in a new method.SOLUTION: A space section formed of a rim 11a and a tire 12 is divided into two in the width direction by an annular partition wall 13. In other words, two air chambers 23 and 24 are formed of the rim 11a, tire 12, and partition wall 13. A first rim valve 25 and a second rim valve 26 for injecting air to a first air chamber 23 and a second air chamber 24 are attached on the rim 11a, respectively. A first air pressure sensor unit 3 is built in the first rim valve 25, and a second air pressure sensor unit 4 is built in the second rim valve 26. |
