SOLUTION: The hollow tube is constituted of a first structural member and a second structural member. The first structural member has a first groove part composed of first and second sidewall parts and a first bottom part. The second structural member has a second groove part composed of third and fourth sidewall parts and a second bottom part and having outer width smaller than the inner width of the first groove part. Third and fourth groove parts are formed between the first and second sidewall parts and the outer sides of the third and fourth sidewall part, respectively. A brazing filler material is filled in the third and fourth groove parts. COPYRIGHT: (C)2010,JPO&INPIT |
