That is, the second straight surface 23 S2 is a cylindrical surface. This facilitates the insertion of the support 4 into the vent hole 21. This is because the radial position of the support 4 is stabilized during insertion. In particular, in the present embodiment, such a second straight surface 23 S2 reaches the edge on the inner space 22 side of the inner peripheral surface 23. This means that the edge does not protrude radially inward. Thereby, when inserting the support body 4 in the ventilation hole 21, it is prevented that the friction with the edge and the support body 4 (claw 28) becomes large.

- the outer diameter D 2 is smaller than the diameter D 1 on the side. That is, the dimensions of the housing body 20, the support 4 and the seal ring 8 are determined so that the diameters D 1 and D 2 satisfy this magnitude relationship, and the material of the seal ring 8 is selected. Therefore, when the ventilation member 10 is attached to the housing body 20, the seal ring 8 is landed at a location that is inclined with respect to both the axial direction and the radial direction on the inner peripheral surface 23, and then the inner peripheral surface 23.

- the gas can flow through the internal space 22, the through hole 3, the gas permeable membrane 2, the space AR 1 , the space AR 2, and the external space 24 in this order or reverse order.
- the foreign matter is trapped by the gas permeable membrane 2 unlike the gas.
- the flange 34 of the cover 6 prevents foreign matters (liquid, dust, etc.) from going straight from the external space 24 to the space AR 1 along the radial direction. That is, the collar portion 34 constitutes a maze structure for preventing foreign matters from reaching the gas permeable membrane 2. According to this configuration, the gas permeable membrane 2 is hardly damaged. In the present embodiment, the liquid bounced back to the collar portion 34 can be smoothly discharged out of the ventilation member 10 through the inclined surface 37 of the support 4.
