PROBLEM TO BE SOLVED: To provide a horizontal force distributed anchor device for a bridge, which allows smooth expansion/contraction of a bridge upper structure in a bridge axial direction, and exerts sufficient cushioning function. SOLUTION: The horizontal force distributed anchor device is formed of an anchor 11 fixed to a lower structure 10 (an abutment 1 and a pier 2), and a cushioning body 20 arranged around the anchor 11 and fixed to the bridge upper structure 3. The longitudinal cushioning body 20 has an elliptic anchor through hole 21 in a bridge axial direction in which the anchor 11 is penetrated, and the anchor through hole 21 and the anchor 11 define a gap therebetween in the bridge axial direction, whereby the bridge upper structure 3 is freely expandable/contractible in the bridge axial direction.
