Abstract

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.

First claim

The invention claimed is:

1. A case in which a housed object is to be housed in a housing space, the case comprising:
a first case body in which a channel that extends from a region serving as the housing space is formed,
wherein 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 that connects the first channel portion and the housing space, the second channel portion having a channel-side opening that is open to the first channel portion and

the channel-side opening having a second-side opening edge spaced apart from a first-side opening edge, wherein the second-side opening edge is an edge on a second outlet side of the first channel portion and is located nearer to the housing space than the first-side opening edge, and the first-side opening edge is an edge on a first outlet side of the first channel portion.

2. The case according to claim 1 ,
comprising a second case body that is integrated with the first case body, wherein a portion of the second outlet is formed in the second case body,
wherein a boundary between an outer wall surface of the first case body and an outer wall surface of the second case body is located at a lower position than the second outlet.

3. The case according to claim 1 , wherein the first channel portion includes a portion that is bent toward the second channel portion between the first outlet and a portion connected to the second channel portion.

4. The case according to claim 1 , wherein the size of an opening of the second channel portion that faces the first channel portion is smaller than the size of an opening of the second channel portion that faces the housing space.

5. The case according to claim 4 , wherein the second channel portion is bent.

6. The case according to claim 2 , wherein the first channel portion includes a portion that is bent toward the second channel portion between the first outlet and a portion connected to the second channel portion.

7. The case according to claim 2 , wherein the size of an opening of the second channel portion that faces the first channel portion is smaller than the size of an opening of the second channel portion that faces the housing space.

8. The case according to claim 3 , wherein the size of an opening of the second channel portion that faces the first channel portion is smaller than the size of an opening of the second channel portion that faces the housing space.
