PROBLEM TO BE SOLVED: To provide a stopper device for limiting the displacement of a structure, and a cushioning packing used for the stopper device enhancing cushioning performance to impact. SOLUTION: The stopper device 2 for limiting the displacement of the structure is constituted by providing a lower stopper member 3 with an upward protrusion 5, providing an upper stopper member 4 with a downward opening recess 7, and arranging the upward protrusion 5 in the downward opening recess 7, wherein impact force in case of an earthquake is cushioned by the cushioning packing fitted to the upward protrusion. The cushioning packing used for the stopper device 2 for limiting the displacement of the structure is a composite structure type cushioning packing 1 comprising a cylindrical packing body part 14 of annular cross section formed of a soft elastic material, and hard elastic parts 16 arranged embedded in a peripheral sidewall part in the cylindrical packing body part 14. The hard elastic parts 16 are arranged embedded to extend in the vertical direction of the cylindrical packing body part 14, and formed as hard elastic parts harder than the cylindrical packing body part 14.
