PROBLEM TO BE SOLVED: To provide a joint gasket having a surface lip projected sideways from up and down ends of a core and an internal lip and put on a vertical joint and a horizontal joint between external wall materials of a building, improving the external appearance of a part exposed from the surface lip bent in a recessed shape in the case of being put on the joints in a crossing section of the vertical joint and the horizontal joint, eliminating a gap between the back of the internal lip of one gasket and the end face of the surface lip of the other gasket abutting thereon, increasing a sealing property, and at the same time, preventing a shadow from being formed. SOLUTION: An intermediate lip 25 is projected sideways from the core 22 between the surface lip 23 and the internal lip 24. Each lip is formed longer in the order of the internal lip 24, the surface lip 23 and the intermediate lip 25, and when they are pushed in joints 11 and 12 to be put on, the internal lip 24 bent in a recessed shape covers the surface lip 23, and it is exposed from the surface lip 23 bent in a recessed shape in the crossing section. The back of the internal lip in the exposed part has the same color as that of the surface of the external water material to eliminate a sense of incompatibility. COPYRIGHT: (C)2004,JPO&NCIPI
