To inexpensively provide a vertical buffer anchor pin for buffering vibrations of a bridge during earthquakes, by facilitating manufacture and construction.
A vertical buffer anchor pin 3 is inserted into an abutment from a hole 4a of a flange 4 with a predetermined thickness, which is protrusively provided on a lateral surface of a main girder of a bridge, so as to buffer horizontal vibrations of the main girder with respect to the abutment. A positioning material 6 is fixed to the vertical buffer anchor pin 3 in a position corresponding to the hole 4a. An elastic body ring 7 made of a rubber molding is inserted from the top of the anchor pin 3 until it abuts on the positioning material 6 in the hole 4a, and fixed to the vertical buffer anchor pin 3 by being tightened from a position above the elastic body ring 7 via a washer larger in diameter than the hole 4a by means of a nut 12.
