To provide a mounting structure of a pneumatic pressure detection device, easy in mounting work.
The present invention is a vehicular wheel 10 in which a second sub air chamber member 13B incorporating a sensor unit 30 in a tire air chamber, is fixed on a peripheral surface 11d of a well part 11c. The vehicular wheel 10 has: a first vertical wall surface 15 formed to erect from the peripheral surface 11d of the well part 11c outward in the wheel diameter direction and extend to the wheel circumferential direction of the peripheral surface 11d; and a second vertical wall surface 16 formed in the well part 11c to face the first vertical wall surface 15. The sub air chamber member 13B, having a sub air chamber SC formed therein, and a communication hole 13b for communicating the sub air chamber SC and the tire air chamber MC, is fitted between the first vertical wall surface 15 and the second vertical wall surface 16, and its both edges 13c, 13c are respectively locked to the first vertical wall surface 15 and the second vertical wall surface 16, respectively.
