SHADOW MASK SUPPORT FRAME

摘要

PURPOSE:To easily make bimetal behave by using various metals independently. CONSTITUTION:A shadow mask support frame 29 consists of the high and low thermal expansion metal plate pieces 30 and 31 which are mutually arranged in parallel at the hook section 32 with the engagement section 321 which is fit in the panel pin planted on the panel so as to be used jointly with a spring member. At the end section on the reverse side of the engagement section 32 of the metal plate pieces 30 and 31, an overlapping section 36 in which the low thermal expansion metal plate piece 31 overlaps with the high thermal expansion metal plate piece 30 is provided. Further, a concave section 37 in which the high thermal expansion metal plate piece 30 is fit is provided at the low thermal expansion metal plate piece 31 which corresponds to the high thermal expansion metal plate piece 30 of this overlapping section 36.
