Claims

[Scope of utility model registration request]

A jig body that supports a plurality of electrodes having electron beam transmission holes so that each electron beam transmission hole is arranged substantially in a straight line, and a fixture that is fixed to the jig body and regulates the interval between a pair of adjacent electrodes. a spacer, a movable spacer that is movable in the axial direction of the electrode and is inserted between other electrodes to regulate the electrode spacing; and a movable spacer that is inserted into the electrode from one end in the electrode arrangement direction to arrange the electron beam transmission holes in a straight line In a device that includes a core metal that presses the electrode to make it come into close contact with each spacer, and a pressing body that presses the electrode from the other end in the arrangement direction of the electrodes and makes it come into close contact with each spacer, there is a difference between both sides of at least one movable spacer in the movable direction. The same magnetic polarity as the facing surface of the movable spacer is imparted to the jig main body portion facing the surface near the fixed spacer, and the same magnetic polarity as the opposing surface of the movable spacer is imparted to the jig main body portion facing the surface far from the fixed spacer. An electron gun assembly jig characterized by being provided with different magnetic polarities.
