る。In this embodiment, when the breather body 2 is mounted in the mounting hole formed by the through hole, one side of the retaining flange 6 that engages with the inner surface of the axle housing is formed into the flat surface 5 that is substantially orthogonal to the axis of the mounting hole. The other side is inclined and the notch 8 adjacent to the flat surface 5 of the retaining flange 6 is formed over the entire circumference of the breather main body 2, and the opening 8a of the notch 8 on the retaining flange 6 side is formed. The one end edge 8b intersects with the flat surface 5, and a part of the bottom portion 8c of the notch 8 connected to this one end edge is located inside the flat surface 5 in the axle housing. More specifically, the retaining flange 6
Has a cross-sectional shape in which a lower surface 6b is an inclined surface and a "shib" shaped notch 8 having a flat surface 5 is formed on the upper portion 6a side.
