STRUCTURE BODY
Document Type and Number:
Japanese Patent JP2001205461
Kind Code:
A
Abstract:
To make a structure body made by joining members having two face plates and a rib which connects the face plates by a friction stir joining light in weight.
The tip parts of face plates 21 and 22 of a hollow shape member 20 are connected by a rib 24, and joined with the tip parts of the face plates 11 and 12 of a hollow shape member 10 by a friction stir joining method. The visible outline of the joined part of the tip part of the face plate 21 (22) and the rib 24 is formed by circular arcs 31 (33) and 32 (34) which are recessed towards the side of the hollow shape member 20. The diameter of the circular arc 31 (33) is smaller than the diameter of the circular arc 32 (34). Thus the structure body is made light in weight.
