In the recess of the cover, fluid shock buffer blades are formed on at least a portion, which is urged by foot fingers and swelling foot finger roots, the blades being slanted in a direction perpendicular to the longitudinal direction of the cover. The marginal portion of the cover is fused to the marginal portion of the bottom plate.
