PROBLEM TO BE SOLVED: To provide a bearing side block less deforming horizontally until it is broken, enabling the easy estimation of a breaking load, and having excellent restorability. SOLUTION: This rubber bearing side block installed at a connection part between an upper structure and a lower structure. A slit-like groove is formed from a side compressed by the actio of a bending moment by a horizontal force in earthquake toward a side tensed by the action of the bending moment. The tip of the slit-like groove is extended at least to near a neutral axis when the bearing side block in which the slit-like groove is not formed receives the bending moment.
