Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0026] figure 1 It is a front view showing the schematic configuration of the gasket 1 according to the embodiment of the present invention, figure 2 Yes figure 1 A-A sectional view of the gasket 1 shown. In the following, for ease of explanation, figure 1 , 2 One side (the arrow a direction) in the direction of the axis Y1 (hereinafter also referred to as the axis Y1 direction), which is the axis of the washer 1 in the middle, is the upper side, and the other side (the arrow b direction) is the lower side. And, with figure 1 , 2 One side (the direction of arrow c) in the radial direction extending perpendicular to the axis Y1 of the washer 1 is the inner peripheral side (the side of the space enclosed and closed by the washer 1), and the other side (the direction of arrow d) is Peripheral side. In the following description, when describing the positional relationship an...

Abstract

Provided are a gasket and a sealing structure that are able to further suppress the speed of corrosion of a member that pinches the gasket. In a gasket (1), an upper gasket member (10) and a lower gasket member (20) are disposed opposite to each other. The upper gasket member (10) is provided with an annular plate-like upper base (13), an upper outer-circumference section (14) extending obliquelyupward (a-arrow direction) from the outer circumferential edge (13d) of the upper base (13), an upper outer-circumferential-side annular section (15) that is annular plate-like shaped and that extendsfrom the outer circumferential edge (14d) of the upper outer-circumference section (14) toward the direction (radial direction (c- and d-arrow directions) along which the upper base (13) extends. Further, the lower gasket member (20) is provided with an annular plate-like lower base (23), a lower outer-circumference section (24) extending obliquely downward (b-arrow direction) from the outer circumferential edge (23d) of the lower base (23), and a lower outer-circumferential-side annular section (25) that is annular plate-like shaped and that extends from the outer circumferential edge (24d)of the lower outer-circumference section (24) toward the direction (radial direction (c- and d-arrow directions)) along which the lower base (23) extends.

Description

Technical field [0001] The invention relates to a gasket and a sealing structure, in particular to a gasket and a sealing structure used in vehicles, general equipment and the like. Background technique [0002] In vehicles and general-purpose equipment (for example, automobiles), gaskets are used in order to seal a case in a device that houses an engine and electronic parts inside. The gasket, for example, is clamped in a compressed state between a pair of members that are combined to form the housing to be elastically deformed, thereby realizing the seal between the pair of members and realizing the sealing of the housing. [0003] The car may drive in a coastal area or an area sprayed with deicing agent. At this time, salt water or snow melting agent may adhere to the parts of the automobile, and the salt water or snow melting agent may enter the gap between the members for clamping the gasket and remain. Residual salt water or snow melting agent may cause corrosion of the cla...
