PROBLEM TO BE SOLVED: To provide a joint gasket in which an appearance is not damaged and sealing properties are not damaged by protruding a seal lip from a joint even when the depth and width of a joint width are changed while sealing properties are not damaged by preventing the generation of a rolling of a fixed quantity or more. SOLUTION: The joint gasket is composed of pole sections 22, the seal lips 23 and 24 projected from both sides of the pole sections 22 and a lip 26 for preventing the rolling connected at the joint-inserting side ends of the pole sections 22 at a central section in a breakable manner by a connecting section 25. The seal lips 24 are brought into contact elastically at corner sections on the chamfered interior side of an outer wall material 29 and seal the corner sections, and an inundation to the indoor side can be prevented. The lip 26 for preventing the rolling has support lips 31 and projecting sections 32. Even when the gasket 21 is charged under the state in which the gasket is inclined to the joint 28, the lip 26 is brought to the state in which the lip 26 is abutted against the end face of the outer wall material and straddled, and is not inclined more than that.
