Summary:PURPOSE: A sleeve for diffusing stress is provided to prevent local damage due to the crack and deformation of a wall around a penetrating hole in advance. CONSTITUTION: A sleeve(10) for diffusing stress comprises a sleeve cylindrical body and a plurality of ring ribs(14). The ring rib is protruded on the outer circumference of the sleeve cylindrical body by being shaped into a disk in order to diffuse compressive stress. The sleeve receives a compressive force by the tension of an earth anchor(110) while being embedded into a concrete wall(100), receives compressive bearing stress from a compressed surface, and diffuses maximum stress through a ring rib.
