Document Type and Number:
WIPO Patent Application WO/2018/181996
Kind Code:
A1
Abstract:
This method for manufacturing a starting device case which has at least one curved portion and into which oil is supplied is a method in which a thickened portion is formed by thickening a portion of a metal plate, and forming the curved portion by subjecting the plate to a pressing process to bend the thickened portion. An outer surface of the curved portion projects to the outside of the case further than a curved surface concentric with an inner surface of the curved portion of which the radius of curvature is the sum of the radius of curvature of said inner surface and the thickness of the plate forming the case. Metal flow in the curved portion is continuous without interruption between the inner surface and the outer surface.
