Abstract: A vacuum gate valve includes a casing having an opening, and a valve plate that swings in the casing to open/close the opening. The vacuum gate valve further includes a position adjuster for bringing the valve plate into close contact with the casing when the valve plate is in a position where it entirely closes the casing opening. The position adjuster includes a rise/lower element for moving up and down inside the casing to come into contact with the valve plate and adjust the valve plate's position, and a raising/lowering unit for raising/lowering the rise/lower element inside the casing without friction resistance being generated between the rise/lower element and the casing.
