KNOB STRUCTURE FOR ELECTRIC MACHINE TO PREVENT ECCENTRIC COMBINATION OF EXTERNAL OPERATING KNOB WITH KNOB HOLE OF FRONT PANEL

摘要

PURPOSE: A knob structure is provided to prevent the eccentric combination between a knob and a hole and to realize the more stable design by inclining the knob and the hole. CONSTITUTION: A bore of a hole(30) is formed in an inclined face to be expanded inward. An external diameter of a knob(50) to be installed in the hole is formed in an inclined face to be reduced a diameter from a protruding face of a function switch portion. Thereby, the combining eccentricity of the knob and the hole is prevented.
