<p>PROBLEM TO BE SOLVED: To reduce the number of parts and to reduce assembly time by providing an tilting obstruction part in a projection shape for obstructing a screw from being tilted to an outer side on the boss for fixation of a case. SOLUTION: For the R wall surface 4a of a projection part 4, an outer wall is present in a range equal to the nominal diameter 7d of a tap pin screw 7 or more than the nominal diameter provided with a slight gap and it is not projected to the range smaller than the nominal diameter 7d of the tap pin screw 7. The side wall surfaces 4b and 4c and outer wall surface 4d of the projection part 4 can be any shape in the range of not interfering a liquid crystal display 6. A top surface 4e is present at a position for not exceeding the height of the upper surface 8a of a seat 8 for the fixation in the state of placing the liquid crystal display 6 to the boss with screw tilting prevention. The tilting and falling of the screw are supported by the R wall surface 4a and the liquid crystal display 6 is fixed without a liquid crystal display fixture. As a result, the parts, the fixture of the liquid crystal display 6 for instance, are abandoned and assemblability is substantially improved like the reduction of the number of the parts and the reduction of the assembly time, etc.</p> |
