To extensively use a suction cup at a place narrow and hard to put a hand in, a place not to reach out, a hidden place which cannot be seen, etc., only by devising it possible to remove the suction cup only by pulling a cord.

A lateral hole 2 is opened on a connecting part of a double suction cup 1, A cord 3 is inserted into the hole and one end of the cord is adhered on an end of a suction surface of the suction cup. A small suction cup 4 is adhered on the other end of the cord. The small suction cup is put out at a place free to reach out. When the cord on which the small suction cup is attached is pulled, one end of the suction surface of the suction cup adhered on an end of the opposite side of the cord is rolled up, air enters, and the suction cup is removed.
