う問題があった。Further, in the configuration disclosed in Japanese Patent Application Laid-Open No. 7-4875, an intake duct is provided for rainwater that jumps on the ground during heavy rain, or that is hit laterally by a storm or a building wind or jets of rainwater that blows upward. The filter attached to the opening or the outside air intake port (Claim 3) has a certain prevention effect by absorbing moisture, but the protection effect against a strong jet is insufficient as in the conventional example. There is a possibility that the jet flow may pass through the intake duct as in the above-described conventional example at the intake port without the filter (except for the third embodiment). And the rainwater jet that blows upward cannot easily prevent the water from flowing into the enclosure because There is a problem that there is a possibility of troubles occur.
