定されている。 Further, in this embodiment, the inner circumferential wall surface 3a of the retaining wall 3 forming the circumferential wall surface of the recess 4 is rounded (or may be an inclined surface) with a predetermined radius of curvature, as shown in FIG. 5 or FIG. It is formed. The wall thickness of the peripheral edge of the rubber profile 5 gradually becomes thinner toward the outside, and is set so that the amount of compressive deformation of the peripheral edge of the rubber profile 5 during tile molding is as small as possible. .
