## 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.

## Claims

### Claim 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, and
out of opening edges of the second channel portion that face the first channel portion, a second-side opening edge that is an edge on a second outlet side of the first channel portion is located nearer to the housing space than a first-side opening edge that is an edge on a first outlet side of the first channel portion is.

### Claim 2 (depends on 1)

The case according to claim 1,
comprising a second case body that is integrated with the first case body, a portion that serves as the second outlet being 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 is.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)

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

### Claim 6 (depends on 2)

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.

### Claim 7 (depends on 2)

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.

### Claim 8 (depends on 3)

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.
