PROBLEM TO BE SOLVED: To enhance operational reliability when slidably moving a body frame with an elevating/lowering platform being mounted thereon with respect to a chassis frame of a vehicle by using a hydraulic cylinder mechanism in which two hydraulic cylinders facing opposite to each other are arranged in parallel.SOLUTION: An underfloor-stored lifting apparatus includes a body frame 10 slidable with respect to a vehicle, a hydraulic cylinder mechanism 15 for retracting the body frame under the vehicle floor, a foldable elevating/lowering platform 60 with its top face being flat in a deployed state, and an elevating/lowering link mechanism disposed on the body frame 10 side and driving the platform 60 in an elevating/lowering manner. A support rail 90 is fixed in the longitudinal direction of the body frame 10, and a sliding body 92 slidably brought into surface contact with the support rail 90 is fixed to at least one of cylinder body parts 81a, 82a to prevent any posture change of the cylinder body parts in the rotational direction. |
