Connection of a plate and tubular members

摘要

The invention is directed to a connection of a plate and a pair of tubular members. The plate has an aperture defined therein, and a tubular flange portion which is formed around the aperture and which extends away from a plane of the plate. A first opening end portion of a first tubular member is fitted onto an outer circumferential surface of the flange portion of the plate. And, a second opening end portion of a second tubular member is inserted into the flange portion, with a region of the second opening end portion axially remote from an end thereof pressed into contact with an inner circumferential surface of the flange portion. It is arranged that at least a part of an outer surface of the second opening end portion between the end of the second opening end portion and the region is pressed into contact with an inner surface of the first tubular member. An expanded portion may be formed between the region and the end of the second opening end portion to press the second tubular member into contact with the inner surface of the first tubular member.
