A vacuum fixing device for parts, comprising a small pad portion 1 and a large pad portion 2, which are different in diameter from each other and each formed therein with suction paths and provided on one and the same axis, wherein the small pad portion 1 is switched over to the large pad portion 2 or vice versa. When a small part 14 is sucked, a movable shaft 11 of the large pad portion 2 is slid downwardly, and suction is performed through a suction path 3 of a small pad 4 and a suction path 5 of a fixed shaft 7, and, when a large part 15 is sucked, the suction is performed through both suction routes including a route through a suction path 8 of a large pad 9, a suction path 10 of the movable shaft 11, and air paths 6 and a suction path 5 of the fixed shaft, and another route through a suction path 3 of the small pad 4 and a suction path 5 of the fixed shaft 7.
