摘要:
A manifold gasket of the invention is used for sealing around manifold holes of a manifold, wherein at least three manifold holes are arranged side by side. The gasket is formed of a first metal plate extending around the manifold holes to constitute a manifold gasket, and two spacers attached to two longitudinal end portions of the plate. The first metal plate includes first holes corresponding to the respective manifold holes, and beads situated around the respective first holes for sealing therearound. Each spacer includes a second hole greater than an outer shape of the bead to allow the bead to be situated inside the second hole. The thickness of the spacer is less than the height of the bead. Thus, the manifold gasket can be securely fixed to an engine part through the spacers without creep relaxation of the beads, while the bead not surrounded by the spacer absorbs deformation of the manifold by heat.
