摘要： PROBLEM TO BE SOLVED: To maintain a sure sealing function for space between a cylinder head and a cylinder block. SOLUTION: A stacked gasket 5 is formed out of plates 7 and 8 as seal members, and a plate type member 11 fitted between the plates 7 and 8. The third bearing parts 7F and 8F as support parts are formed on the outer boundary of the half-bead parts 7B and 8B of the plates 7 and 8. When the stacked gasket 5 is laid in space between a cylinder head 6 and a cylinder block 1, the third bearing parts 7F and 8F come in contact with the plate type member 11, thereby maintaining the proper sealing function of the contact part. Also, the third bearing parts 7F and 8F function as support parts, and the first bearing parts 7C and 8C, as well as the second bearing parts 7D and 8D strongly adhere to the cylinder head 6 (cylinder block 1), and the sealing function of the contact part is thereby maintained certainly.

摘要： PROBLEM TO BE SOLVED: To suppress the oil rise or seal failure of a gasket by the deformation of a cylinder wall caused by a large temperature difference by suppressing the collision of the cooling water carried into a water jacket through a cooling water passage with the combustion chamber-side upper part of the cylinder wall.
SOLUTION: A cylinder block 1 has the water jacket 4 formed so as to open to the upper surface of the cylinder block and surround the circumference of the cylinder wall 3, and the water cooling passage 5 for supplying cooling water to the water jacket. A protruding piece 21 is provided protrusively into a connection part 5b constituting the passage 5, and this protruding piece 21 prevents the cooling water carried through the passage 5 from directly cooling the upper part of the cylinder wall 3. By providing the protruding piece, the excessive cooling of the cylinder wall of a high temperature can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent the excessive deformation of a half bead in assembling to heighten sealing performance by disposing an elastic seal member between the half bead and a bead in a gasket forming the half bead comprising an inclined part and the bead projected in arc shape in this order from the end part on a combustion chamber hole side. SOLUTION: This cylinder head gasket 1 interposed between a cylinder head 3 and a cylinder block 4 of an internal combustion engine has a base 10 formed by punching an elastic metal plate such as a stainless steel plate and provided with a plurality of combustion chamber holes 11, cooling water holes, and a plurality of bolt holes around the combustion chamber holes 11. The bead 13 projected in arc shape is formed by pressing around the combustion chamber hole 11, and the half bead 14 reaching a flat part 14a via an inclined part is formed on the inner peripheral side of the bead 13. In this case, an elastic seal member 30 is stuck between the bead 13 and the half bead 14 and made to act as a stopper to prevent the excessive compressive deformation of the half bead 14.

摘要： PURPOSE:To obtain a metal gsaket which maintains the high sheet performance by making the bead part of one bead plate to the thinner plate thickness and/or lower hardness than that of the bead part of the other bead plate. CONSTITUTION:The bead plate 1a on a cylinder head side has a plate thickness of 0.2-0.25mm thinner than the bead plate 1b on a cylinder block side having a common plate thickness of 0.25-0.3mm, and each of the beads 5a and 5b has the equal width of 1.5-2.5mm. When a metal gasket thus formed is tightened by a prescribed force, the bead 5b on the cylinder block side becomes flat because a prescribed force acts, while the bead 5a on the cylinder head side is deformed largely in comparison with the case of the bead 5b, because of the thinner plate thickness, and the top part of the bead 5b after deformation is fitted.

摘要： PURPOSE:To secure the stabilized sealing property over the whole circumference of fluid holes without applying excessive stress to the top of a bead of a board, to which any metal ring is not joined, even in the case where a bead at the same width is formed in each board. CONSTITUTION:A laminated metal gasket has a first metal board 10 and a second metal board 20, in which fluid holes 11, 21 for passing the pressurized fluid are drilled and beads 13, 23 are formed in the periphery of the fluid holes. A metal ring 14 at a predetermined width is joined between the bead and the fluid hole of the first board 10, and the first and the second boards 10, 20 are arranged so that the top of each bead faces to each other. In this case, the bead of the second board 20 is formed at a height (b) lower than the height (a) of the bead of the first board 10 at the time of forming the bead, and thereafter, the beads of the first and the second boards are practically compressed to the same height.

摘要： PURPOSE:To bond a first and second paint layers containing a prescribed amount of vulcanizing agent properly on a metal base plate respectively and secure a seal property maintaining the durability of these paint layers. CONSTITUTION:A first paint layer 2 containing a prescribed amount of a vulcanizing agent required in a vulcanization hardening is bonded on at least one surface of a metal base plate 1 and also a second paint layer 3 containing a prescribed rate of vulcanizing agent not filling to 1 in relation to a prescribed amount of vulcanizing agent is bonded on this first paint layer 2 and the first paint layer 2 and the second paint layer 3 are vulcanized. This second paint layer 3 maintains such hardness as not flowing out and is stuck to the first paint layer 2. A favarable seal property is secured in relation to a joint surface due to rich flexibility.
