PROBLEM TO BE SOLVED: To easily and reliably perform work for mounting a hydraulic cylinder mechanism that slidably moves a body frame mounted on a lifting platform with respect to a chassis frame of a vehicle and prevent the posture of the hydraulic cylinder mechanism from being changed due to deflection of a piston rod.SOLUTION: An under floor storage type elevating apparatus includes the body frame 10 slidable with respect to the vehicle, a hydraulic cylinder mechanism 15 for retracting the body frame under the vehicle floor, a foldable lifting/lowering platform 60, and a link mechanism disposed on the body frame 10 side and driving the platform 60 for lifting/lowering. The end of a piston rod 81b of the hydraulic cylinder mechanism 15 is reliably held by a mounting element 100 by fitting of tapered surfaces without looseness. Thus, the piston rod 81b is positively supported in a horizontal direction, so that the posture of each cylinder 81, 82 can be prevented from being changed due to deflection of the piston rod. |
