Patent ID: 7306237

Claim:
A sealing material for an ant groove that is fitted to the ant groove made in a surface of either one of a pair of members, that is in a joint place between these members and that makes contact with a surface of the member facing the ant groove, thereby sealing both of the members, with the sealing material comprising: an elastically deformable material; and a sectional shape having: a straight bottom edge which is disposed on a bottom face of said ant groove, with said straight bottom edge having a first end and a second end; an arched convex edge which makes contact with the surface of said member facing said ant groove; a first projecting edge which connects with said first end of said straight bottom edge and projects obliquely outside from said first end of said straight bottom edge; a concave inlet portion which is located between said first projecting edge and said arched convex edge; a second projecting edge which connects with the second end of said straight bottom edge and is composed of straight lines, with the second projecting edge projecting obliquely outside from said second end of said straight bottom edge; a straight sloping edge of which one end connects directly with an end of said arched convex edge that is opposite to said first projecting edge and of which the other end connects directly with said second projecting edge; and a corner portion which is found in a connecting portion of said second projecting edge and said straight sloping edge; wherein: when the sealing material for the ant groove is fitted to said ant groove, said concave inlet portion is disposed on an opening edge of the ant groove, and then an entirety of the sealing material for the ant groove is made to gyrate toward an inside of the ant groove around said concave inlet portion as a base point, so that the sealing material for the ant groove gets pressed into the ant groove in a state where a periphery of said corner portion is elastically deformed.
