PROBLEM TO BE SOLVED: To efficiently transfer a vibration load from one frame to another frame by regulating backlash of a gap even if the gap is formed in a spot-welded portion.SOLUTION: A nugget n is formed in a spot-welded portion between a front face of a front pillar 2 and a welding surface 6a formed in a rear end of a front upper frame 6, and a gap t is formed in the spot-welded portion by the nugget n. In a tension plate 12, a pitch P1 between stopper holes 13 formed in both ends thereof is set shorter than a pitch P2 between screw holes 6b, 2c formed in the front upper frame 6 and the front pillar 2. Therefore, when the front upper frame 6 and the front pillar 2 are connected by the tension plate 12, a tension load is generated, thereby regulating backlash between the front upper frame 6 and the front pillar 2. |
