<p>PROBLEM TO BE SOLVED: To flatly attach a pillow function to a bottom for bed or the like in case of non-use and to hold that function while inclining and protruding it in case of use. SOLUTION: A groove 2 is formed near the end face of a back bottom 1a orthogonal to the lengthwise axis of the bottom. A planarly rectangular recessed part 3, of which the cross section is formed triangular, is formed closer to the center of the back bottom 1a, and a lid member 4 is freely attachably and detachably fitted to this recessed part 3. By having plural projecting wires 5 on an upper surface 4o of the lid member 4 and fitting an edge part 4e to the groove 2, the upper surface 4o is held so as to be protruded while being inclined.</p> |
