<P>PROBLEM TO BE SOLVED: To reduce attachment members, to simplify a shape of a metal mold and to reduce manufacturing costs by forming a part to which a U-shaped cathode tube is attached in a simple shape. <P>SOLUTION: A second supporting part 42 has a U-shaped frame body 421, a locking part 43 and pedestal parts 422 disposed sandwiching the locking part 43. Side parts of long tube parts 301 in the vicinities of connected parts of the long tube parts 301 with a short tube part 302 abut on the U-shaped frame body 421, and an upper part of the short tube part 302 abuts on curved surfaces 423 of the pedestal parts 422 and a lower part of the short tube part 302 abuts on a curved surface 433 of the locking part 432, so that the short tube part 302 is supported. <P>COPYRIGHT: (C)2008,JPO&INPIT |
