Abstract
Disclosed is a deflection yoke comprising: a fastening band of a ring shape assembled on an outer periphery of a neck portion in a coil separator by a fixing manner, provided for being extended and contracted; a pair of flanges bent and extended from both ends of the fastening band, on which a through hole is formed; a yoke clamp for generating fastening force by tightening of a bolt for passing through a pair of through holes, then being tightened by a nut; a bending portion projected on an outer side along the periphery of the fastening band, whose object contact plane for coming in contact with an outer periphery of the neck portion is divided into at least two or more.
