1. A drive device, comprising:
an electrical component which controls an electric motor;
a base member which includes an arrangement surface on which the electrical component is arranged and a side surface extending annularly around a first parallel arrangement direction in which the arrangement surface and the electrical component are arranged;
a cover member which includes a top portion having an inner ceiling surface facing the electrical component in the first parallel arrangement direction and a wall portion having an inner wall surface extending annularly around the first parallel arrangement direction in a vertically extending manner from the inner ceiling surface in the first parallel arrangement direction;
a connecting unit which connects the base member and the cover member in a fitting manner; and
protrusions which are disposed on the side surface, and are less deformable than the wall portion, wherein
the protrusions include a first protrusion and a second protrusion protrude in parallel in an opposite direction each other on a second parallel arrangement direction along a plane perpendicular to the first parallel arrangement direction so as to come in contact with the inner wall surface.
