Abstract
A suction pad includes a body and a sponge member. The sponge member made of a material having a semi-open and semi-closed cell structure includes a plurality of cavities opening toward a workpiece, a tubular stopper attached to the body is disposed in each of the cavities of the sponge member, and a suction passage formed in each stopper communicates with a negative pressure chamber formed in the body. The height of the stopper is set to a dimension that prevents the sponge member from being compressed to a maximum compression amount and allows the sponge member to be compressed until the sponge member exhibits airtightness.
