Abstract: A workpiece support provides enhanced reliability of operation and enhanced durability. The workpiece support comprises a rod, a sleeve body, a case member, a scraper, an external peripheral hydraulic chamber, and oil passages, and is further provided with an air passage formed between the rod and the internal peripheral surface of the sleeve body, and connected to the small gap between the rod and the scraper, and an air input port for supplying compressed air to the air passage; wherein compressed air is supplied from the air input port to the air passage and expelled from the small gap between the rod and the scraper when the rod is retracted.
