Description of the Related Art In recent years, a method of adsorbing an object with an adsorbing pad utilizing a vacuum suction action and handling it has been generally used for moving and cargo handling of the object. FIG. 3 is a cross-sectional view of a conventionally used adsorption pad, 1 is a vacuum container having a cup shape and having an open end 2, 3 is a connection port for connecting to a vacuum device (not shown), and 4 is a hoist.

材５として、ネオプレンゴムスポンジを用いている。Conventionally, hard rubber is generally used for the vacuum sealing member 5. However, when a suspended load having a relatively large air leak is vacuum-adsorbed and lifted, the surface of the suspended load is rough or rough. The vacuum sealing member 5 is made of hard rubber and does not easily come into a concave surface, and a gap is formed so that the vacuum sealing member 5 cannot be adsorbed. Therefore, a neoprene rubber sponge is used as the vacuum sealing member 5.

することは現在の技術では不可能である。However, the neoprene rubber sponge is relatively soft and has a large sealing effect by appropriately conforming to the surface of an object to seal irregularities. However, when the surface of the suspended load of the other product is rough and hard, the friction is fast, and the corners (Fig. 3A) are easily worn out and become unusable. Moreover, it is impossible with the present technology to mold a rubber having the softness of the neoprene sponge (rubber hardness of about 15 ° to 20 °).
