PROBLEM TO BE SOLVED: To eliminate waste pollution by eliminating the need for resin molding of a grip and to make its exchangeable use possible. SOLUTION: Grip pieces 3 are arranged successively on both length-wise sides of a sheet piece 1 made in a rectangular form or a flat V-shaped strip form by using a thick Western paper via a diagonal fold line 2 expanding upwardly to form a spreading structure of the grip. The sheet is folded longitudinally against the rigidity thereof to put the grip pieces together at a joint parts 4 from the diagonal fold lines thereby forming a downwardly tapered cylindrical body 5 while the grip pieces are clasped together. The cylindrical body is fitted into a downwardly tapered cup 6 with the lower diameter thereof shorter and the upper diameter thereof larger than the upper inner dimension thereof and the downwardly tapered outer circumferential surface of the cup is received almost vertically on the downwardly tapered inner circumferential surface of the cylinder body thereby holding a cup with the grip pieces.
