PROBLEM TO BE SOLVED: To suppress a vibration generation apparatus from being broken owing to a horizontal shock by improving impact buffering properties for buffering against the horizontal shock when a rod-like member abuts against an inner periphery of an insertion hole.SOLUTION: An upper frame 2 is provided with an upper horizontal plate part 22 which extends in a horizontal direction. A lower frame 3 is provided with a lower horizontal plate part 33 which extends in the horizontal direction opposite the upper horizontal plate part 22 in a vertical direction. A swing stop device 5 has a hexagonal bolt 50 which has its lower end side fixed to the lower horizontal plate part 33 while having an upper end side inserted into the insertion hole 23a provided in the upper horizontal plate part 22, and a swing stop buffer rubber 55 which is provided for the hexagonal bolt 50 to suppress a vertical swing of the upper frame 2. In the insertion hole 23a, cylindrical aluminum metal fittings 26 are fitted, the fittings having an axial length larger than the thickness of the upper horizontal plate part 23. |
