Claims

[Claims for Utility Model Registration] A substantially cylindrical holder that is fitted onto the neck of a cathode ray tube and is provided with magnetic locking portions at positions spaced apart from each other in the axial direction, each having a predetermined magnetic pole structure, and A magnet holding structure in an electron beam adjusting device comprising a plurality of substantially ring-shaped magnets rotatably fitted between two magnet locking portions of the holder, the magnet holding structure comprising: An elastic holding piece is formed at a predetermined position, and a protrusion that projects outward from the outer peripheral surface of the holder and has a substantially wedge-shaped cross section is formed at the tip of the holding piece, and one of the plurality of magnets is formed at a predetermined position. A magnet in an electron beam adjusting device, characterized in that the protrusion is positioned between two magnets that are to be separated from each other, and the slope of the protrusion is brought into elastic contact with the inner peripheral edge of one of the two magnets. holding structure.
