PURPOSE:To facilitate the welding work of an interior angle joint by securing a triangular piece on the tip of a slanted framework member and welding and coupling it to the framework of a car body. CONSTITUTION:A triangular piece 6 is fixed in advance on the tip of a slanted framework member 3 by welding and such. Then, it is welded 4 to the intersection of a longitudinal framework 1 with a lateral framework 2. As a result, since a setting angle theta1 can be increased and a welding rod is easy to enter when the piece is welded, welding work may be facilitated. |
