PROBLEM TO BE SOLVED: To easily combine and fix a frame having a window of various sizes to a displaying body by the first movable body, which is provided in a frame body housing the display body, to be extensible outward. SOLUTION: Recess parts 4 are formed at plural places on the rear side of a frame body 3; the bottom surface of s spring 5 is arranged on the part 4; a cross section is formed stepwise like vertical parts 6, 8 and a horizontal part 7. A first movable body 13 consists of e.g. horizontal part movable bodies 14, 15, vertical part movable bodies 16, 17, etc. The bottom surface of the body 14 is abutted on the upper surface of the spring 5. Plural second engaging parts 18 are formed at proper places on a right side surface; a recess part 19 is formed on a left and upper side surface; a left and lower side is abutted on the part 6 of the body 3. When the pushing part 12 of the button 9a is not pressed, the engaging part 11 of a button 9a is engaged with the second engaging part 18 of the body 13 (the body 14). When the pressing part 12 of the button 9a is pressed, this engaging is released. Thus, the size of the external shape of the movable body can optionally be adjusted.
