摘要： PROBLEM TO BE SOLVED: To provide a vacuum device having a reliable vacuum indicator. SOLUTION: The vacuum device 5 comprises a vacuum pump 10, and the vacuum indicator 15. The vacuum pump is composed of a cylinder, a piston arranged in the cylinder 50, a piston rod 60 fixed to the first end of the piston and extending through one end of the cylinder, the piston rod 60 reciprocatingly movable in the axial direction so that the piston is reciprocatingly movable in the cylinder toward a first direction and a second direction opposite thereto in the axial direction, a sealing ring 85 arranged on and around the piston and engaged with the inner wall of the cylinder throughout its outer periphery, a stopper means extending from the piston outward to the radial direction, the stopper means having a base-end stopper means located near the base end face of the piston and a terminal-end stopper means located near the terminal end face of the piston.
