Abstract: The present invention relates to a sucker and an adhesion arrow having the same. More particularly, the present invention provides a sucker that can be attached, instead of a needle, to an arrow for a toy arrow shooter. The sucker of the present invention is formed with an annular projection on an adhesion surface of the sucker. Thus, even when the sucker collides against a target at a high speed, the sucker can be prevented from bouncing back from the target due to a repulsive force generated from the collision and thus securely adhere to the target. Further, even though the sucker of the present invention flies and collides against the target at a certain angle, the sucker can easily adhere to the target. Further, the sucker is made of a soft material so that a repulsive force can be smaller than an adhesion force when the sucker collides against the target.

Abstract: A suction cup system facilitates the holding and manipulation of sensitive objects such as printing plates without scratching, marring or damaging surfaces of the objects. The system has a flexible thin sheet made of polyester or similar material. The flexible sheet is stretched over the flexible contact flange of a suction cup and supported in position by a relatively rigid frame.
