摘要： A cylinder head gasket 1 includes a shim ring 5 which surrounds a combustion chamber opening 2A in a gasket body 2. The shim ring is circumferentially spot welded along weld lines 5a, 5b. The weld spacing of the spot welding is varied to provide zones H1, H2 and H3 of high welding density and zone of a low welding density. The weld spacing in the zone of high welding density is such that a distortion in the shim ring is produced under the influence of heat generated during the welding operation if the weld spacing is used around the full circumference of the shim ring for spot welding. However, by interposing a zone of a low welding density, a distortion in the shim ring can be prevented while increasing the welding strength.

摘要： A cylinder head gasket (1) is provided with a shim ring (5), which surrounds a combustion chamber hole (2A) of a gasket body (2). The shim ring is spot welded circumferentially along weld lines (5a, 5b) such that pitches of the spot welding are varied to form high weld density regions (H, H, H) and low weld density regions in a circumferential direction of the shim ring. Pitch of spot welding in the high weld density regions is one which would generate strain in the shim ring due to heat at the time of welding in the case where the entire circumference of the shim ring were spot welded at such pitch. Inclusion of the low weld density regions can prevent strain in the shim ring to enhance a welding strength.
摘要翻译：气缸盖垫片（1）设置有围绕垫圈主体（2）的燃烧室孔（2A）的垫片环（5）。垫片环沿着焊接线（5a，5b）沿周向点焊，使得点焊的节距变化以在垫片环的圆周方向上形成高焊接密度区域（H，H，H）和低焊接密度区域。高焊接密度区域中的点焊的间距是在垫片环的整个圆周以这种间距点焊的情况下，由于焊接时的热而在垫片环中产生应变的点。包含低焊接密度区域可防止垫片环中的应变增强焊接强度。

摘要： PROBLEM TO BE SOLVED: To press the base part of each taper part against laminated other gasket board simultaneously with press of the tip part of each taper part against a cylinder head or a cylinder block by the explosion pressure of an engine SOLUTION: A cylinder head gasket 1 is provided with a first and second gasket boards 2 and 3 arranged on the outer side, and each gasket board is provided with taper parts 2a and 3a protruding in a direction in which the taper parts are separated away from each other and having the protrusion side narrowed; and a seal ring 6 arranged inside the two taper parts and making contact with the inner peripheral surface of each taper part. Bent parts 2c and 3c protruding to the seal ring side are formed on the respective taper parts. When the bent part is pressed to the outer peripheral side through the seal ring 6 by an explosion pressure, the tip part of the taper part is pressed against a cylinder head 7 or a cylinder block 8, and the base parts of the taper parts are pressed against each other. This constitution improves sealability of respective parts by the press force.
