JOINT STRUCTURE FOR TUBULAR MEMBER

摘要

PROBLEM TO BE SOLVED: To prevent deformation and breakage of even coupled tubular members of different coefficients of thermal expansion. SOLUTION: This joint structure is for two tubular members formed from materials of different coefficients of thermal expansion and coupled at opposed ends. An end 3a of one of the two tubular members is held between an end 2a of the other tubular member and a clamping member 5 secured to the end 2a of the other tubular member. The clamping member 5 is formed from the same material as the other tubular member or a material of a substantially identical coefficient of thermal expansion to that of the material thereof. The end 3a of the one tubular member is flared out in a direction perpendicular to the axis.
