ELECTRON GUN ASSEMBLING JIG

PROBLEM TO BE SOLVED: To provide an electron gun assembling jig capable of reliably positioning a plurality of small spacers without assembling them and improve the workability and positioning precision. SOLUTION: In an electron gun assembling jig 31 for positioning electrode parts 39 to be installed in an electron gun of a cathode-ray tube, a presser member to be brought into contact with the electrode parts 39 from the outside in the direction at right angles to the tube axis is installed and a pair of pinching members 35, 37 for pinching the electrode parts 39 through the presser member and positioning the electrode parts 39 in the direction at right angles to the tube axis are also installed. Projected parts 40 to be brought into contact with the end parts of the electrode parts 39 in the tube axis direction are formed in the pair of the pinching members 35, 37.
