PURPOSE: To enable not only height adjustment but also adjustment of horizontal positions and to eliminate the danger of damaging a support member during the adjustments. CONSTITUTION: If a front panel 2 need be lowered, a plus screwdriver is turned by a height adjustment bolt 10. In this case, it is important that the level of a hook member 15 remain unchanged, and the height adjustment bolt 10 is lowered by a dimension (h), together with a bracket 6 and the front panel 2, by being threaded into a nut 16. Since the structure does not cause the end of the height adjustment bolt 10 to touch a support member 25, the support member 25 is in no danger of being scratched. |
