Abstract
In a color picture tube device of the electromagnetic deflection in-line electron gun type including a color picture tube with a neck portion and funnel portion and a deflection yoke device mounted near the joint between the neck portion and the funnel portion and provided with a deflection yoke assembly having an inner diameter sufficiently larger than the joint neck and funnel portion such that the deflection yoke can move in a direction perpendicular to the tube axis, the deflection yoke device comprises supporting means for supporting the deflection yoke assembly having a first portion movable along the neck portion and a second portion disposed substantially perpendicular to the first portion but tiltable with respect to the tube axis, means for securing the deflection yoke assembly to the second portion of the supporting means, and at least two wedge means inserted and fixed in a gap between the funnel portion and the deflection yoke assembly.
