。[Scope of Claim for Utility Model Registration] 1. Pushing one side of the opening of a bearing hole drilled in the caliper and one of the friction pads rotatably inserted into the bearing hole and placed facing each other with a disc rotor in between. A seal structure for a vehicle disc brake in which a dust seal is installed between the camshaft shaft and the outer annular seal portion of the dust seal is fitted into a groove inside the bearing hole to seal the bearing hole, the dust seal comprising: An annular lip is formed on the inner periphery of the outer end protruding from the bearing hole, and the outer periphery of the camshaft is sealed all around the inner periphery between the annular lip and the opening surface of the bearing hole. An inner annular seal portion is formed to protrude, and a protrusion is provided on the inner periphery between the inner end disposed in the bearing hole and the opening surface of the bearing hole, and the protrusion penetrates the protrusion in the axial direction of the bearing hole. 1. A seal structure for a disc brake for a vehicle, characterized in that an air passage is formed and the annular lip portion, inner annular seal portion, and protrusion are brought into contact with the outer peripheral surface of a camshaft. 2. A dust seal is installed between the opening of the bearing hole drilled in the caliper and a camshaft that is rotatably inserted into the bearing hole and pushes one side of the friction pads that are arranged facing each other across the disc rotor. In the seal structure of a disc brake for a vehicle, the outer annular seal portion of the dust seal is fitted into a groove inside the bearing hole to seal the bearing hole. An annular lip portion is formed on the inner periphery of the end portion, and an inner annular seal portion is formed protruding from the inner periphery between the annular lip portion and the opening surface of the bearing hole to seal the entire outer periphery of the camshaft. In addition, a plurality of protrusions and air passages are formed alternately in the circumferential direction on the inner periphery between the inner end disposed in the bearing hole and the opening surface of the bearing hole, so that the annular lip portion and the inner circumference are formed alternately in the circumferential direction. A seal structure for a disc brake for a vehicle, characterized in that an annular seal portion and a protruding portion are brought into contact with the outer peripheral surface of a camshaft.
