Metal laminate gasket with engaging device having curved edges

A metal laminate gasket adapted to be engaged with an engaging projection of an engine part for immovably locating the gasket on the engine part, comprising,

• a first metal plate including at least one first hole for receiving therein the engaging projection of the engine part, and a plurality of first curved engaging portions and first curved non-engaging portions alternately arranged to each other to define the first hole, said first curved engaging portions having first curved inner edges for forming a first imaginary hole with a diameter smaller than a diameter of the engaging projection, and said first curved non-engaging portions having a size greater than the engaging projection, and
• a second metal plate situated above the first plate, said second plate including at least one second hole corresponding to and located above the first hole, and a plurality of second curved engaging portions and second curved non-engaging portions alternately arranged to each other to define a second hole, said second curved engaging portions having second curved inner edges for forming a second imaginary hole with a diameter smaller than the diameter of the engaging projection, said second curved non-engaging portions having a size greater than the engaging projection, each of said first and second curved non-engaging portions having a curvature extending in the direction radially outwardly from a center of each curved non-engaging portion to provide a narrow width for each curved engaging portion sandwiched between two curved non-engaging portions, said first and second curved engaging portions, when the first and second plates are assembled, being arranged not to completely overlap with each other so that when the gasket is placed on the engine part, the first and second curved engaging portions are easily bent and engage the engaging projection to prevent disengagement of the gasket from the engaging projection.
