摘要

A case is provided with a drainage channel that smoothly drains water while also being able to suppress the intrusion of water into a housing space. The case includes a first case body in which a channel extending from a region serving as the housing space is formed. The channel includes a first channel portion having one end side connected to a first outlet and another end side connected to a second outlet, and a second channel portion connects the first channel portion and the housing space. Out of the opening edges of the second channel portion that face the first channel portion, a second-side opening edge, which is the edge on the second outlet side of the first channel portion, is located nearer to the housing space than a first-side opening edge, which is the edge on the first outlet side of the first channel portion, is.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is the U.S. national stage of PCT/JP2016/052410 filed Jan. 28, 2016, which claims priority of Japanese Patent Application No. JP 2015-029623 filed Feb. 18, 2015.

TECHNICAL FIELD

The present invention relates to a case provided with a drainage channel.

BACKGROUND

As disclosed in JP 2002-134939A noted below and the like, cases disposed in an environment that has large variations in temperature, such as a vehicle-mounted case for housing an electrical device, are sometimes provided with a channel for the drainage of water produced by the condensation of water vapor.

Such cases need to have a structure in which water cannot easily intrude into the housing space that houses a housed object, while also ensuring the function of smoothly draining water through a channel.

A problem to be solved by the present invention is providing a case with a drainage channel that smoothly drains water and can suppress the intrusion of water into the housing space.
