Both ends of synchronous links 20 are connected to the second arms (b) of a pair of bell crank levers 11, 12 arranged in the longitudinal direction of a vehicle via pivot shafts 21, 21. A front bracket 22 and a rear bracket 23 aligned in the right and left directions of the vehicle are fixed to a front frame and the load carrying platform 17 respectively, and both ends of an interlocking link 24 extended in the right and left directions of the vehicle are connected to the brackets 22, 23 via ball joints 25, 26.
