<p>PURPOSE:To improve workability/controllability and to enable the handling of a small commodity by providing a space whose volume varies by the movement of a plunger, inside a cylinder and providing a communication hole opening to the space and passing to a space inside a suction pad in the direction almost orthogonal with the moving direction of a plunger. CONSTITUTION:When a pusher 2b is pushed by a finger after first sticking a suction pad 5 to a body 7 to be sucked, a plunger 2 moves inside a cylinder 1, the volume of a space A is increased, the air pressures of the space A, communication hole 1P, hole 4p and space C thereby become lower than an atmospheric pressure and the body 7 to be sucked is sucked to the suction pad 5. When the pressurizing of the pusher 2b by a finger is suspended, the plunger 2 is returned to the original position by the restoring force of a spring 3 and the air pressures of the space A - space C return to an atmospheric pressure, so the suction force is eliminated and the body 7 to be sucked is released from the suction.</p> |
