Abstract

A vacuum suction apparatus is equipped with a body having a supply port, and a pad provided on a lower portion of the body to which a workpiece can be attracted under suction. The pad is constituted from a base plate accommodated in a space of the body, a flexible intermediate plate provided on a lower portion of the base plate, and a suction sheet body disposed on a lower portion of the intermediate plate and having a sheet that attracts the workpiece under suction. In addition, the base plate, the intermediate plate and the suction sheet body are stacked along an axial direction of the body. The rigidity of the base plate is highest, whereas the rigidities of the intermediate plate and the suction sheet body are lower in this order, and the flexibilities thereof are greater in this order from the base plate.
