造。[Claims for Utility Model Registration] 1. A cylindrical wheel hub is rotatably attached to the outer periphery of an axle shaft via a spindle,
This wheel hub has a
It has a flange to which the wheel is attached, and
The axially outer part of this flange becomes a large-diameter deceleration case part in which a deceleration mechanism that decelerates the rotational force of the axle shaft and transmits it to the wheel hub is housed inside, and the inner part is connected to the spindle via a bearing. In a vehicle wheel portion that is a small-diameter bearing portion that is supported by a brake disc and is provided with a brake disc, the root portion of the flange of the wheel hub on the reduction case side has a diameter smaller than that of the reduction case portion. 1. A ventilation structure for a vehicle wheel portion, characterized in that a concave portion is formed by narrowing the concave portion, and a ventilation hole is provided at a base portion of a flange facing the concave portion. 2. The ventilation structure for a vehicle wheel portion according to claim 1, wherein the ventilation holes are provided at a plurality of locations in the circumferential direction of the wheel hub. 3. The ventilation structure for a vehicle wheel portion according to claim 1 or 2, wherein axial ribs are provided at a plurality of locations in the circumferential direction of the wheel hub within the concave portion.
