ABSTRACT:
A spiral wound gasket having an annular body serving as a centering member which is integrally disposed at the inner periphery side of a gasket body formed by winding, in the form of a spiral. The gasket body comprises a metal hoop material and a filler material overlapping each other. When this gasket is disposed at fit-joint-type pipe connection portions of the exhaust pipe system in a motor vehicle, the annular body serves as a centering member to prevent the gasket body from protruding into the fit joint. This prevents the gasket body from deterioration and damage, thus assuring a high sealing property for a long period of time. Further, merely by inserting and fitting the gasket, the gasket may be automatically aligned and positioned with respect to the fit joint. Further, the inner peripheral surface of the gasket body and the annular body form an annular closed space, thus making the entire gasket into a lightweight design.
