FIELD: machine building.SUBSTANCE: metal cap (1) comprises an arched section (2) forming the bearing surface, left and right flange sections (3) which are placed and connected with the opposite ends of the arched section (2), bush sections (4) placed so that to rest on the back surfaces of the left and right flange sections (3) and through which assembling bolts are inserted, and a recess (12) formed between the two bushes (10). Each of the bush sections (4) is formed with a recess (12) and includes two holes (11) for a bolt passing through each of the flange sections (3), and two bushes (10) embracing the holes (11) for the bolt. The bushes (10) are interconnected by a rib (13) placed so that to be able of crossing the recess (12) between the bushes (10) on the front end face side.EFFECT: provision of a cap that shall be cast inside a light-metal element as a frame and that provides for the reduction of bearing surface deformation and is suitable for improving the connection with the light-metal element.4 cl, 8 dwg |
