Abstract
Official abstract text for this publication.
Provided is a resin cover removal structure for removing a resin cover attached to a metallic body, where the body and the resin cover are attached to each other in such a manner that a body-side attachment surface formed on a peripheral edge portion of the body and a cover-side attachment surface formed on a peripheral edge portion of the resin cover face each other, a part of at least one of the body-side attachment surface and the cover-side attachment surface is cut off to provide an insertion groove opened outside a peripheral edge portion thereof, the insertion groove is inclined in such a manner that a distance between the body and the resin cover decreases toward the inside of the peripheral edge portion, and the resin cover can be removed from the body by inserting a wedge-shaped tool into the insertion groove.
First claim
Opening claim text (preview).
What is claimed is: 1. A resin cover removal structure for removing a resin cover attached to a metallic engine body, wherein the engine body and the resin cover are attached to each other in such a manner that a body-side attachment surface formed on a peripheral edge portion of the engine body and a cover-side attachment surface formed on a peripheral edge portion of the resin cover face each other, a part of at least one of the body-side attachment surface and the cover-side attachment surface is cut off to provide an insertion groove opened outside a peripheral edge portion of the part, the insertion groove is inclined in such a manner that a distance between the engine body and the resin cover decreases toward the inside of the peripheral edge portion, and the resin cover is removable from the engine body by inserting a wedge-shaped tool into the insertion groove. 2. The resin cover removal structure according to claim 1 , wherein the tool is thinned toward a tip at an inclination angle equal to or greater than the inclination of the insertion groove, and the tool is inserted into the insertion groove in a direction parallel to the body-side attachment surface to separate the resin cover from the engine body. 3. The resin cover removal structure according to claim 2 , wherein a gasket is provided on the interior side from the insertion groove. 4. The resin cover removal structure according to claim 2 , wherein the insertion groove is provided on the cover-side attachment surface. 5. The resin cover removal structure according to claim 4 , wherein a gasket is provided on the interior side from the insertion groove. 6. The resin cover removal structure according to claim 1 , wherein the insertion groove is provided on the cover-side attachment surface. 7. The resin cover removal structure according to claim 6 , wherein a gasket is provided on the interior side from the insertion groove. 8. The resin cover removal structure according to claim 6 , wherein the resin cover comprises the insertion groove. 9. The resin cover removal structure according to claim 1 , wherein a gasket is provided on the interior side from the insertion groove. 10. The resin cover removal structure according to claim 1 , wherein the resin cover is a cylinder head cover or a chain cover.
