摘要： PROBLEM TO BE SOLVED: To prevent large distortions from occurring in a resin frame. SOLUTION: With regard to a first positioning hole 18A and a first positioning hole 18B substantially immobile to a sheet metal frame 18, a female screw hole for fixing 18C and a female screw hole for fixing 18D are provided respectively near the first positioning hole 18A and the first positioning hole 18B. A second positioning hole 18E and a second positioning hole 18F, allowing only displacement in a specified direction, are provided, respectively at positions more separate from the first positioning hole 18A and the first positioning hole 18B than the female screw hole for fixing 18C and the female screw hole for fixing 18D, and also the resin frame is pressed against the sheet metal frame 18 side on an outer periphery side of the resin frame. As a result, since the resin frame can be prevented from becoming fatigued at an early stage, large distortions are prevented from occurring in the resin frame, while obtaining a full holding force.
