Abstract:

PURPOSE:To prevent breakage of an annular part by inserting a medium body between the annular part and a tubulous member and further expanding the member so that these three are united in one body. CONSTITUTION:After fixing a steel medium body 6, equipped with at least more than one interlocking part 8 on the inner peripheral face, to the inside of an annular part 2 such as a cam piece or the like, a tubulous member 1 made of ductile material such as steel, copper, aluminium alloy or the like is positioned through said medium body 6, then, after letting a tube expanding jig pierce into the tubulous member 1, the exterior of said member 1 is interlocked with the interlocking part 8 of the steel medium body 6. By providing said body 6, stress due to expansion of the tubulous member is alleviated and the annular part 2 is prevented from breakage.
