Structure and method for joining extruded members.

摘要

1. A joint structure including an extrudate member and a rod-like mating member, in which the extrudate member has a closed sectional structure portion and has an end thereof joined to the rod-like mating member such that the extrudate member intersects a longitudinal direction of the rod-like mating member. The extrudate member includes a joint portion integrally provided at an end thereof and adapted to be matched to the shape of an outer surface of the mating member to wrap the mating member. The joint portion is bonded to the outer surface of the mating member at its longitudinally intermediate portion by a brazing, a spot-welding or the like.
