Abstract
A holder elastically supporting a mask frame of a shadow mask has a holder body and a bimetal plate. The holder body is formed by bending an elongate metal plate in two opposite directions along first and second bending lines inclined at an angle to the longitudinal axis of the holder body, and has an engaging portion in engagement with a stud pin, a fixed portion fixed to the mask frame, and a slope portion extending aslant between the engaging portion and the fixed portion. The holder body moves the mask frame toward a phosphor screen along the central axis, when the mask frame is thermally expanded. The bimetal plate includes a first metal plate on the mask-frame side and a second metal plate on the holder-body side, the first and second metal plates having different thermal expansion coefficients and being stuck together. The bimetal plate is located between the fixed portion and the mask frame, for moving the mask frame away from the phosphor screen along the central axis of the face panel when heated.
