PROBLEM TO BE SOLVED: To provide a switch-operating knob structure, which has an excellent quality and is manufactured at an increased workability and economic factor. SOLUTION: In the inside of a cylinder frame opened at both ends and formed cylindrically, shape, there is integrally formed a partition which is formed parallel to an axial center of the cylindrical shape and serves to divide the inside of the cylinder frame into a chamber receiving an indicator- illuminating light source, and a chamber receiving a display section-illuminating light source. Further, one end of the partition is formed of a first molded portion of a light-non-transmitting resin material, and a second molded portion of a light-transmitting resin material. The first molded portion consists of a protruding end by which one end of the partition is protruded beyond a circumference of an opening at one end of the cylinder frame. The second molded portion is two-color molded integrally with the first molded portion, in such a manner that it is extended to the circumference of the opening at the one end of the cylinder frame to block the opening, and the protruding end of the partition is embedded in the second molded portion.
