PROBLEM TO BE SOLVED: To reliably fix a needle 1 having a needle handle 2 on the side of its proximal end and a resin needle tube 3 in the state of inserting the needle 1 into the needle tube 3 with a part of the needle handle 2 projecting from the needle tube 3. SOLUTION: A flexible engaging piece 4 forming a forked part 5 at its distal end part is provided projecting outward in a radial direction from the end on the side of the needle handle 2 of the needle tube 3.In the state of bending the engaging piece 4 to fold back in a U-shape, the needle handle 2 is pressurized to the inner wall of the needle tube 3 by the round part 5a of the forked part 5 to fix the needle handle 2 and the needle tube 3. Furthermore, a wedge 6 formed projecting at the engaging piece 4 is put into a gap between the needle handle 2 in the needle tube 3 to be fixed. COPYRIGHT: (C)2006,JPO&NCIPI
