RUBBER BEARING AND PILE HEAD STRUCTURE

PROBLEM TO BE SOLVED: To provide a rubber bearing and a pile head structure for reducing bending moment generated in a joining part of an upper structure and a lower structure with a simple constitution. SOLUTION: This rubber bearing 10 is formed by arranging bearing rubber 13 composed of a rubber elastic body superior in compression restoration property between a projecting upper bearing part 11 fixed to a lower part of a footing 1 and a recessed lower bearing part 12 fixed to a head part of a foundation pile 2. A projecting side surface of the upper bearing part 11 and a recessed inner peripheral surface of the lower bearing part 12 are joined by side receiving rubber 14; a void 14G is arranged between a lower end part of the side receiving rubber 14 and a recessed bottom surface of the lower bearing part 12; and a friction coefficient is reduced in a contact surface of the side receiving rubber 14 and the upper bearing part 11.
