Claims

[Scope of Claim for Utility Model Registration] (1) In a deflection yoke in which a lever-shaped horizontal deflection coil is provided along the inner circumferential surface of a bobbin shaped like a bobbin, the inner circumferential surface of the bobbin along which the horizontal deflection coil runs A rib supporting the horizontal deflection coil is provided to protrude,
A deflection yoke characterized in that a heat dissipation space is formed between the inner peripheral surface of the bobbin and the horizontal deflection coil. (2) The deflection yoke according to claim 1, wherein the ribs are formed in a circumferential direction on the inner peripheral surface of the bobbin and are composed of a plurality of ribs. (3) The deflection yoke according to claim 1, wherein the rib is formed in the axial direction of the inner circumferential surface of the bobbin and is composed of a plurality of ribs.
