ABSTRACT:
A driving section case for a linear actuator comprises a body having a front portion and a rear portion, the front portion having a cylinder assembly protruding therefrom, and the rear portion having an opening providing access to the interior of the body; and a cover closing said opening; the opening having a bottom edge, a top edge, and side edges, the top edge being located forward in relation to the bottom edge, and the side edges being inclined, whereby the opening faces both upwardly and rearwardly; the body having an outer surface surrounding the opening, said outer surface extending both downwardly and forwardly from the location of the opening; and the cover having a flange extending entirely around its periphery and overlying at least the part of said outer surface immediately adjacent to the opening. The flange, in cooperation with the inclined opening of the body, prevents the entry of rain water into the interior of the case in the event of failure of a seal between the cover and the case body. The inclined opening also allows easy access to electrical terminals located near the bottom of the interior of the case body, when the cover is removed.
