Distal ends of the both side parts are overlapped on the other side of the body to form a connecting portion. A whole part of an internal surface of the wrapping sheet faces the body and is bonded to an external surface of the body through hot melt adhesives. A usage amount of the hot melt adhesives bonds the wrapping sheet and the body together and is larger at least in a region of both end portions in a width direction on the other side of the body than on the one side of the body.
