<p><P>PROBLEM TO BE SOLVED: To provide a ventilation member capable of lowering the possibility of infiltration of water and oil or the like into a housing. <P>SOLUTION: A ventilation member 1A is attached to a cylindrical screw shaft 12 forming an opening 11 of a housing 10, and comprises: a support 2 provided with a screw hole 21 to be screwed to the screw shaft 12; a waterproof ventilation film 3 supported by the support 2 to face the opening 11; and a seal member 4 for sealing a gap between the housing 10 and the support 2 around the opening 11. By the configuration, since the support 2 has a shape of being spread to the outer side of the screw shaft 12, fluctuation when fastened by the screw shaft 12 is reduced. Also, the screw shaft 12 provided on the housing 10 itself achieves a role of a protective wall for stemming inflow of water and oil or the like from a surface of the housing 10 into the opening 11. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
