Abstract

An electronic control unit includes a substrate, a first cover, and a second cover. An electronic component is mounted on the substrate. The first cover is disposed to be opposed to one surface of the substrate and includes a first sidewall part extending in a direction perpendicular to the substrate, and claw part(s) projecting laterally from the first sidewall part. The second cover is disposed to be opposed to the other surface of the substrate and includes a second sidewall part, and groove part(s). The second sidewall part faces the first sidewall part. The groove part(s) is formed at the second sidewall part such that a shape of each of the groove part(s) when viewed from the direction perpendicular to the substrate is a recessed shape in conformity with a projecting shape of a corresponding claw part. Each groove part is fitted to a corresponding claw part.

First claim

What is claimed is:

1 . An electronic control unit comprising:
a substrate on which an electronic component is mounted; a first cover that is disposed to be opposed to one surface of the substrate and that includes:
a first sidewall part extending in a direction perpendicular to the substrate; and
at least one claw part projecting laterally from the first sidewall part; and
a second cover that is disposed to be opposed to the other surface of the substrate and that includes:
a second sidewall part facing the first sidewall part; and
at least one groove part that is formed at the second sidewall part such that a shape of each of the at least one groove part when viewed from the direction perpendicular to the substrate is a recessed shape in conformity with a projecting shape of a corresponding one of the at least one claw part, wherein each of the at least one groove part is fitted to a corresponding one of the at least one claw part.

2 . The electronic control unit according to claim 1 , wherein:
one of the first cover and the second cover is a resilient body; and the other one of the first cover and the second cover is a non-resilient body.

3 . The electronic control unit according to claim 1 , wherein when viewed from the direction perpendicular to the substrate, an end surface of each of the at least one claw part has a circular arc shape.

4 . The electronic control unit according to claim 1 , wherein the second sidewall part includes:
a wall surface on which the at least one groove part is formed; a wall surface that is located on an opposite side of the second sidewall part from the wall surface; and a swelling part that is located on the wall surface and has a projecting shape corresponding to the recessed shape of each of the at least one groove part.

5 . The electronic control unit according to claim 1 , wherein:
the second sidewall part includes at least one convex part each of which projects toward the substrate to have a curved shape; and each of the at least one groove part is formed at a corresponding one of the at least one convex part.
