PURPOSE: To appropriately correct the doming phenomenon of a shadow mask and improve the efficiency of attaching and detaching work of a shadow mask structure. CONSTITUTION: One end of a base member 81 which fixes a suspension spring 8 to a frame of the shadow mask structure, and one end of a spring member 82 which has an inclined section 822 connected to a flat section 821 having a locking hole for lock to a stud pin 9, are joined by a function member 83, where a pull-up angle &thgr; of the inclined section 822 is 9.3° or less. A gap (d) between the skirt side surface of the junction member 83 and the tip end of the stud pin is 1.9 mm or more, preferably 2.4 mm or more. A gap F between the skirt side surface of the junction member 83 and the frame of the junction member 83 is 3.5 mm or less, preferably 3.0 mm or less. A length L of the inclined section 822 is 20 mm or more.
