## Abstract

An electrical device configured to be provided in a vehicle includes a first case; and a second case that is fastened to the first case by a bolt. A side surface of the first case is provided with a columnar projection that extends along the side surface. The columnar projection is provided with a bolt insertion hole through which the bolt is inserted, the bolt insertion hole extending along the side surface. A center line of the bolt insertion hole is located closer to a center of the first case than a center line of the columnar projection is.

## Claims

### Claim 1

An electrical device configured to be provided in a vehicle, the electrical device comprising:
a first case; and
a second case that is fastened to the first case by a bolt, wherein
a side surface of the first case is provided with a columnar projection that extends along the side surface,
the columnar projection is provided with a bolt insertion hole through which the bolt is inserted, the bolt insertion hole extending along the side surface, and
a center line of the bolt insertion hole is located closer to a center of the first case than a center line of the columnar projection is.

### Claim 2 (depends on 1)

The electrical device according to claim 1, wherein:
a formed-in-place gasket is provided between mating surfaces of the first case and the second case; and
in the mating surface of one of the first case and the second case, a groove is provided between the formed-in-place gasket and the bolt insertion hole.

### Claim 3 (depends on 1)

The electrical device according to claim 1, wherein a tab projects from the side surface, and the columnar projection extends along the side surface from the tab.
