摘要： In an auxiliary tool for feeding including a hook portion and wing portions, the hook portion includes a flat plate-like bottom surface portion, a flat plate-like top surface portion separated from the bottom surface portion in the up-down direction so as to be parallel with the bottom surface portion, a side surface portion coupling the bottom surface portion and the top surface portion on the same side, and claw portions extending downward from an end portion of the top surface portion on the opposite side to the side surface portion, and the wing portions extend in forms of V shapes from the side surface portion in the right-left direction and have elastic force to return to their original shapes when compressed such that angles of the V shapes are decreased.
