Title:
RUBBER GASKET
Document Type and Number:
WIPO Patent Application WO/2016/059933
Kind Code:
A1
Abstract:
Provided is a rubber gasket that, having low counterforce, is unlikely to exert an adverse effect such as deformation or strain on a counterpart member, it being possible to improve sealing using the rubber gasket. To achieve this purpose, a rubber gasket is interposed between two members facing each other, the rubber gasket being held in a fitting groove formed in one of the two members, wherein: concave surfaces (11, 13) are respectively formed in a surface (1a) facing the bottom-surface side of the fitting groove and a surface (1b) facing the opposite side, the concave surfaces (11, 13) being positioned in the lateral centers of these surfaces and extending in a circumferential direction, and seal beads (12, 14) are respectively formed on both lateral sides of the surfaces; and the relationship D = 0.025A-0.075A … (1) is satisfied, where D is the maximum depth of the concave surfaces (11, 13), and A is the height between the seal bead (12) facing the bottom-surface side of the fitting groove and the seal bead (14) facing the opposite side.
