CA 2233240

In the setting operation conducted by the handle 90 which is an operating section, an upper portion of the portion 26a' to be pushed of the card 26 is pushed by the end portion of the cam 90b, and the card 26 is moved. In accordance with the movement of the card 26, the suction cup block 23 is elastically deformed, and the suction cup 23b is sucked and held by the body 24 to be sucked. The body 24 to be sucked is composed of a porous body, and air flows from the ventilation hale 29 into a space formed between the suction cup 23b and the body 24 to be sucked, via the body 24 to be sucked. The card 26 is biased ahead by the return spring 27. When the releasing operation is conducted by the handle 90, the cam 90b is rotated, and the end portion of the cam 90b is separated from the end of the portion 26a' to be pushed. After that, when the intensity of the sucking force of the suction cup 23b to the body 24 to be sucked is decreased lower than that of the spring force of the return spring 27, the card 26 is moved ahead, so that the card member 26c pushes up the movable contactor 70.
