PURPOSE: To lighten the breakdown of a cab when a vehicle collides against a front obstacle. CONSTITUTION: An upper bracket 2 relatively large in strength provided under the cab 1 of a truck and an under bracket 4 relatively small in strength provided at a frame 3 are coupled together by a pin 5, and for the frame 3, a stopper 9 is fixed to the rear of the upper bracket 2, and a plurality of windows 6 are made in the upper bracket 2, and also a plurality of slits 10 are made at the stopper 9. Hereby, at the time of collision of a truck, the lower bracket 4 breaks easily, and the upper bracket 2 abuts on the stopper 9, and at that time, by the above window 6b and the slit 10, the upper bracket and the stopper 9 are easy to be plastically deformed longitudinally. |
