PURPOSE: A road seal structure for a hydraulic breaker is provided to prevent damage to a road seal and a piston by minimizing a contact surface of the road seal and the piston. CONSTITUTION: A road seal structure for a hydraulic breaker comprises a buffering installation groove, a road seal installation groove, and a dust seal installation groove. A road seal is inserted into the road seal installation groove. The road seal has an inner vertical surface(10), contacted with a piston, an incline(11), a bottom surface(12), a cut surface(13), an outer vertical surface(14), a slope(15), a top surface(16), and a vertical cut surface(17). |
