摘要:
The method comprises the steps of arranging a first member (5) to be combined, which has a first connecting bore (5A), and a second member (7) to be combined, which has a second connecting bore (7A), in such a manner that one of said members (5) is piled on the other (7) with said first and second connecting bores (5A, 7A) substantially aligned with each other, inserting a connecting member (9) into said first and second connecting bores (5A, 7A) in said first and second members (5, 7) to be combined, and expanding said connecting member (9) to combine said first and second members (5, 7) together via said connecting member (9). Said connecting member (9) may be a tube of a metal not harder than that of said members (5,7) to be combined.
