Minute space being formed between both wings and the side walls of the frame corresponding to the wings and facing and parallel to each other, and slots are inclined at an angle agreeing with a deflecting angle .beta. of an electron beam. Projections are combined with the slots, so that displacement by a thermal expansion of the frame is guided according to the deflecting angle.
