ABSTRACT:
This metal gasket has firmly secured to the intermediate plate through the mounting metal plates the seal members for sealing stepped portions that occur between the cylinder block and the chain case. The metal gasket comprises elastic metal plates formed with notched portions opening to the chain passage opening and an intermediate plate formed with sealing slots, mounting holes and positioning holes. The seal members are installed in the sealing slots of the intermediate plate to seal the stepped portions between the main seal portion and the sub-seal portions. The mounting metal plates attached to the seal members are provided with engagement portions. The engagement portions are folded to hold the edges of the mounting holes to secure the mounting metal plates to the intermediate plate and position the seal members in the sealing slots. Alternatively, the intermediate plates are formed with slots in which to install the seal members, and the elastic metal plates and the intermediate plates are formed with notched portions in areas where the seal members are located. The metal plates securely attached to the seal members are folded to hold the mounting portions of the intermediate plates.
