Abstract

A gasket where a crack is less likely to occur in a seal lip, which improves sealing ability the gasket. A first gasket (10) is installed in a groove formed in a cam cover and seals the gap between a cylinder head and a cam cover. The first gasket has a pair of parallel seal lips (13) in intimate contact with a cylinder head and also has connection sections (15) arranged between the pair of seal lips (13). The connection sections (15) are connected to each of the seal lips (13) and retain, in the vicinity of the connections, the spacing between the seal lips (13).

Description

technical field [0001] The invention relates to a gasket for sealing a gap between two parts. Background technique [0002] An example of a conventional gasket for sealing a gap between two members will be described below with reference to FIGS. 13 to 15. FIG. Fig. 13 is a plan view of a conventional gasket. Fig. 14 is a schematic sectional view of a conventional gasket in an assembled state. The gasket shown in FIG. 14 corresponds to the cross-sectional view taken along line D-D in FIG. 13 . Fig. 15 is a graph showing the relationship between the squeeze ratio and the inter-flange stretch ratio of a conventional gasket. [0003] The conventional example shown is a gasket 500 for sealing the gap between the cylinder head 200 and the cam cover 300 . The spacer 500 is seated in a groove 301 formed in the cam cover 300 . Pairs of protrusions 501 are provided on a side surface of the main body of the spacer 500 spaced apart from each other by a predetermined distance. The ...
