Problems solved by technology

[0009] However, since the spacer 301 and the spacer 401 are formed in vertically asymmetrical shapes, there is a problem that it is difficult to distinguish vertically and an installation error easily occurs in the case of a small volume.

Abstract

A gasket having a cross sectional shape longer than it is wide and is prevented from falling over and bucking. The gasket (1) is installed in an installation groove (2) formed in either of two opposite surfaces and having a cross sectional shape that is longer in the depth direction of the groove than it is wide. The gasket (1) has a meandering section (1a) meandering in the width direction of the installation groove (2) and also has a rib (1b) provided projecting from the inner periphery (1c) and / or the outer periphery (1d) of the meandering section (1a).

Description

technical field [0001] The present invention relates to a gasket, and more particularly to a gasket preferably used in a resin tank. Background technique [0002] In recent years, in order to save space, weight, etc., a resinized and miniaturized counter member to which a gasket is attached has been developed. [0003] Thus, the resinization causes increased tolerances of the counter parts, and the height of the gasket must be increased to secure the gasket's collapse margin. In addition, due to the limitation of miniaturization on the width of the installation groove, the traditional circular cross-section will not be able to meet the expected filling factor, and the width of the gasket installed in the installation groove must be reduced. [0004] Therefore, in recent years, if Figure 6 As shown, the gasket 101 is increasingly supported by being formed into a vertically long cross-sectional shape in which the height is greater than the width (refer to Patent Document 1)....
