Abstract
A deflection yoke mounted on a periphery of a picture tube includes a funnel-shaped resin frame, a pair of deflection coils, and a bias member. The deflection coils oppose each other across a tube axis of the picture tube, each deflection coil has a plurality of winding turns that are loop-shaped and provided along an inner surface of the resin frame, and each deflection coil is composed of (i) a fixed coil that is fixed to the resin frame and includes an outermost of the winding turns, and (ii) a movable coil that is movably provided with respect to the inner surface of the resin frame. The bias member biases the movable coil toward the tube axis.
