Claim 16:
17. The syringe assembly according to claim 15, wherein
the two anti-rotation projected portions respectively have two distal projected portions forming distal sides of the two anti-rotation projected portions, two proximal projected portions forming proximal sides of the two anti-rotation projected portions, and two intermediate projected portions forming spaces between each of the two distal projected portions and each of the two proximal projected portions of the two anti-rotation projected portions,
widths of the two proximal projected portions along the circumferential direction of the distal nozzle portion are respectively larger than widths of the two distal projected portions along the circumferential direction of the distal nozzle portion,
at least the two intermediate projected portions of the two anti-rotation projected portions respectively have two inclined guide portions whose widths along the circumferential direction of the distal end nozzle portion increase toward a proximal direction, and
distal widths of distal ends of the two intermediate projected portions along the circumferential direction of the distal nozzle portion and the widths of the two distal projected portions along the circumferential direction of the distal nozzle portion are smaller than corresponding widths along the circumferential direction of the corresponding distal nozzle portion between the two first column portions and the two second column portions.
