<p>To provide a mounting screw retainer structure which can prevent a mounti ng screw from falling down from a component and can also prevent the interference of the mounting screw with any other related component. In a fastening portion for fastening an upper retaining portion and a lower retaining portion by means of a mounting screw, the upper retaining portion has a screw hole and a cylindrical guide formed around and above the screw hole. Further, a projection is formed on the inner wall of the cylindrical guide at an upper portion thereof. In a loosened condition of the mounting screw where it is disengaged from a screw hole, the head portion of the mounting screw is caught to be retained by the projection. The upper portion of the cylindrical guide is tapered so that it has an inner diameter smaller than t he diameter of the head portion of the mounting screw. Accordingly, even when the upper retaining portion is turned upside down in the loosened condition of the mounting screw, the mounting screw does not fall down from the upper retaining portion. Further, the amount of projection of a lower end portion is small, so that the upper retaining portion can be moved without the interference of the lower end portion with any other related component. This retainer structure is suitable for fastening of acover for an air cleaner bo x whose installation space is narrow.</p> |
