PURPOSE: A volume knob is provided to triply block light emitted from an internal light source, thereby reducing exterior defects of the volume knob. CONSTITUTION: A volume knob comprises a knob outer part(200) and a knob ring(100). The knob outer part is comprised of a second cylindrical shape which includes a first cylindrical protrusion part(210) in the upper surface of the knob outer part. A combining hole(220) which includes a protrusion(230) is arranged in the inside of the knob outer part. The knob ring is comprised of a ring shape in which the protrusion part is inserted in the inside of the ring shape. The knob ring includes an L-shaped hook(110) in a lower surface connected to an upper surface. The hook is combined with the knob outer part while being held in the protrusion of the combining hole. The width between surfaces facing a projected surface in the hook combining process is wider than the width of the hook. |
