A lead 176 is forcedly fitted to the recessed groove 131a of the reinforcing frame 130, and a protective cover 177 is installed in such a manner as to be attachable and removable. The front frame body 110 is formed of a front wall part 110A and an enclosing frame part 110B, and opening parts 111-113 for displaying a big hit generation and determined opening parts such as a liquid crystal television setting opening part 114 are formed on the front wall part 114. A locking device 140 is provided on the reverse side of one side part of the reinforcing frame 130, and bearing parts 137 are mounted on the upper and lower parts of the recessed groove 131 on the base part reverse side. The reinforcing frame 130 is installed in such a manner as to be capable of opening a hinge, so that a hinge receiving space 138 can be formed between the both when the reinforcing frame 130 is fitted into the enclosing frame 110B on the reverse side of the front frame body 110. |
