A cap structure for a radiator used in vehicle is disclosed. The cap includes a main cap body, a connector shaft, and a leak-seal seat. The main cap body includes a metallic cap body and a heat-isolation covering body joined together using screw as a body. The connector shaft is screwed onto the leak-seal seat, and the connector shaft passes through the through hole of a metallic sleeve mounted on the heat-isolation covering body. The side of the protruded rim of the connector shaft urges the end face of the sleeve and a spring is used to mount the connector shaft onto the main cap body. The heat-isolation covering body with a thickness is mounted onto the metallic cap body and two screws are used to lock the metallic cap body onto the heat-isolation covering body to form a unit, and the end side of the covering body is provided with slip-proof teeth and the metallic sleeve is mounted onto the center circular hole.
