<p>An apparatus At for controlling tire inflation pressure is constructed such that, an outlet side end portion 21 a1 of a supplying passageway 21e provided in an axle hub 20 is opened on an outer end surface S1 of a vehicle in a flange portion 21 B of the axle hub 20, and an inlet side end portion 11 al of an introducing passageway 11 a provided in a wheel 11 is opened on an inner end surface S2 of the vehicle in the wheel 11 of a vehicle wheel assembly 10, and by mounting the wheel 11 onto the flange portion 21B, the outlet side end portion 21a1 and the inlet side end portion 11 al are air tightly joined each other. Thus, easiness in mounting the vehicle wheel assembly 10 relative to the flange portion 21 B of the axle hub 20 can be improved.</p> |
