摘要： PURPOSE:To improve the sealing function of an outer peripheral bead and improve reliability by setting the spring constant of a bead formed at the outer peripheral edge part to be relatively smaller than that at the separated part, at the part where the bead approaches within a prescribed distance. CONSTITUTION:The height H of an outer peripheral bead 18 is set lower than the height H2 of other bead 17 at the part where other bead 17 in proximity exists, and set higher than the height H2 at the part where other bead 17 is close, at the part where other bead 17 in proximity does not exist, and the spring constant of the outer peripheral bead 18 is set small at the part where other bead 17 in proximity exists, and set large at the part where other bead 17 does not exist. Since the spring constant of the outer peripheral bead 18 can be varied according to the part where other bead 17 is close or not, the surface pressure due to the outer peripheral bead 18 can be made nearly equal at all parts independently of the existence of other bead 17 in proximity, and the sealing function of the outer peripheral bead 18 can be improved in comparison with that in the conventional.

摘要： PURPOSE:To prevent the damage of a joint face due to a bead and to ensure stable sealing ability on the whole of a metallic gasket by increasing the thickness of a seal film on the surface on the protrusion part side of a bead to a value higher than that of a seal film on the surface on the recessed part side of the bead. CONSTITUTION:First seal films 16a and 16b of a vulcanized rubber layer formed of vulcanized fluorine rubber are formed on both surfaces of a base plate 10. The first seal films 16a and 16b are a seal film adhered on the surface on the protrusion part 15a side of a bead 15 and the surface on the recessed part 15b side thereof, and a thickness t1a of the surface on the protrusion part 15a side of the bead 15 is increased to a value higher than a thickness t1a of the back thereof. Second seal films 17a and 17b of a non-vulcanized or unvulcanized rubber layer formed on both surfaces of the base plate 10 are adhered to the first seal films 16a and 16b, respectively. A thickness t2a of the surface on the protrusion part 15a side of the bead 15 of the second seal films 17a and 17b is increased to a value higher than a thickness t2b of the back thereof. This constitution prevents the top surface of the protrusion part of the bead from being exposed to damage a joint face and ensures stable sealing ability.

摘要： PURPOSE:To secure a stable sealability without being affected by a differential thermal expansion, etc., by welding a shim ring substantially continuously with a substrate along the whole circumference at least close to an inner edge. CONSTITUTION:A metal gasket 1 has a resilient metal plate, that is a substrate 10 of stainless steel, for example, a combustion chamber hole 11, etc., are bored in this substrate 10, and a bead 15, and inclined parts 16-18 are formed in it. A circular metal plate, or a spacer of stainless steel, or a so-called shim ring 20, for example, is fixed to the bead 15 on the side of a protruding part 15. The shim ring 20 is disposed to put its inner edge almost along the inner edge of an aperture end part 10a, and laser welding is performed close to the inner edge. A weld line 21 which is substantially continuous along the whole circumference of the inner edge of the circular shim ring 20 is therefore formed. Penetration of pressure fluid between the shim ring and the substrate can thus be prevented, and a stable sealability can be secured.

摘要： PROBLEM TO BE SOLVED: To contain one end part of a seal member in a recessed part, to increase the thickness of the seal member to a value sufficiently higher than the thickness of a gasket even when the thickness of the gasket is thin, and as a result, to reliably close a step part between a cylinder block and a case even when the step is increased. SOLUTION: A cylinder head gasket 5 is nipped between a cylinder head 2 and a case 4 having a cylinder block 3 and an opening part coupled thereto. The gasket 5 is provided with a through-hole 19 formed in a position situated astride a space between the cylinder block and the case, and a seal member 20 situated in the through-hole. A recessed part is formed in the cylinder head and a position overlapped with the through-hole. One end part of the seal member is situated in the recessed part and the other end part is inserted through the through-hole and brought into elastic contact with the cylinder block and the case.

摘要： PURPOSE:To facilitate discrimination of a seal member by forming the seal member of a material in a color different from that of a base plate. CONSTITUTION:A vulcanized rubber layer 30 composes a seal film, and since it contains carbon block, it is tinted with black. As against above, though first and second seal members 31 and 32 are also formed of vulcanized rubber, both contain carbon black and white carbon, and a silicic acid compound and are colored, and tinted with grey. Since the seal member formed on the base plate is in a color from that of the base plate and discrimination is facilitated, it can be properly visually inspected whether the seal member is formed along a given locus. Further, through utilization of an optical device, automatic inspection is practicable and productivity is improved.

摘要： PURPOSE:To ensure stabilized sealing performance over the entire peripheries of respective fluid holes including the parts in which the plural fluid holes are adjacent to each other. CONSTITUTION:Beads 13 are formed around plural combustion chamber holes 11 drilled in a metal base plate 10, and shim-rings 20 are provided on each inner periphery thereof. Further, flame spray coating layers 22 piled on the shim-rings 20 are provided in specified ranges in which the combustion chamber holes 11 are adjacent to each other. After the beads 13 are compressed to be deformed, the shim-rings 20 and the spray coating layers 22 in the specified ranges are compressed, the shim-rings 20 in other parts are compressed, and thus uniform face bearing pressure can be ensured around the respective combustion chamber holes 11.
