Abstract
A power steering case, including an opening, a lid configured to close the opening of the case, and an O-ring seal disposed in a first annular groove formed in a first inner wall of the lid or of the case, a second inner wall, respectively of the case or of the lid, having a frustoconical shaped portion for progressively compressing the seal before reaching the closed position of the lid where the seal tends to regain a less deformed initial shape in a second annular groove facing the first annular groove and formed in the second inner wall.

A method for attaching a lid to an opening provided in a power steering case, the method comprising steps of:
- inserting the lid into the opening of the case until an O-ring seal disposed in a first annular groove, formed in a first inner wall of the lid or of the case, comes into contact with a frustoconical shaped portion of a second inner wall wall, respectively of the case or of the lid, and
- exerting a pressure on the lid to pass the O-ring seal over the frustoconical shaped portion where it is compressed progressively, until reaching a closed position of the lid on the opening of the case, where the seal tends to regain a less deformed shape in a second annular groove facing the first annular groove and formed in the second inner wall.
