PROBLEM TO BE SOLVED: To provide a spacer pull-out tool which can effectively pull out spacers which is left in an electron gun after beading operation, and is a low cost. SOLUTION: An operator makes chuck levers 3 and a cam mechanism mainly composed of an opening and closing cam 4 approach close to an electron gun (not shown), by pushing an opening and closing lever 11 toward the front, and when they approach to a prescribed distance, the chuck lever 3 is stopped by the action of a stopper 21. After that, by further pushing the lever 11, the opening and closing cam mechanism held partially on to the opening and closing lever 11 operates in the opposite direction, so that the chuck lever 3 closes and pinches each of a plurality of the spacers, then by pulling the lever 11, a plurality of the spacers are simultaneously pulled out of the electron gun, and at the time, the chuck lever 3 is re-opened by the action of the cam mechanism, so that the spacers are left from the electron gun.
