    摘要： A gasket (1) includes a body portion (10) in an annular shape having a basal surface (11) to contact a bottom surface (113) of a groove(110) and a top surface (12) to contact a second member (200) and extending over an entire circumferential direction of the gasket (1), a first protrusion pair (20) protruding from the body portion (10) respectively toward both side surfaces (111, 112) of the groove (110) and extending over the entire circumferential direction; and a second protrusion pair (30) protruding from the first protrusion pair (20) respectively toward both the side surfaces (111, 112). Respective second protrusions (31, 32) of the second protrusion pair (30) are disposed at a same position in the circumferential direction, and tip ends (31f, 32f) of the respective second protrusions (31, 32) are formed in a planar shape to be along the side surfaces of the groove (110). A first gasket width (W1) of the gasket (1) is smaller than a groove width (W0), and a second gasket width (W2) is larger than the groove width (W0).

    摘要： Sealing performance is enhanced. A gasket (1) includes protrusion portions (10, 11) that respectively protrude to contact side surfaces facing each other of the groove to which the gasket is to be attached, an upper side seal lip portion (20) that is formed to contact one of surfaces facing each other between members, a lower side seal lip portion (30) that is formed to contact another one of the surfaces facing each other between the members, and a joining portion (40) that joins the upper side seal lip portion (20) and the lower side seal lip portion (30), wherein the joining portion (40) extends along a virtual straight line (x) in a section of the gasket (1), the upper side seal lip portion (20) has upper side seal lips (21, 22) extending side by side between the protrusion portions (10, 11) in the joining portion (40), the lower side seal lip portion (30) has lower side seal lips (31, 32) extending side by side between the protrusion portions (10, 11) in the joining portion (40), each of the upper side seal lips (21, 22) is tapered, and each of the lower side seal lips (31, 32) is tapered.

    摘要： Provided are a gasket and a sealing structure enabling to exert stable sealing performance even in a case where a sealing target surface is a surface provided with irregularities such as a casting surface.
    A gasket 10 made of a rubber-like elastic body attached to an attaching groove provided in at least one out of two members to seal a gap between these two members includes a first sealing surface 10a coming into surface contact with a surface of a first member out of the two members, a second sealing surface 10b coming into surface contact with a surface of a second member out of the two members, a third sealing surface 10c coming into surface contact with a side surface of the attaching groove, and a pressure receiving groove 11 opened to a side receiving sealing fluid pressure which is an opposite side of the third sealing surface 10c and provided so as to be parallel to the first sealing surface and the second sealing surface.
