PROBLEM TO BE SOLVED: To provide an operation knob which does not require careful attention in operating the knob like a conventional one, and reduces a burden on an operator in operating the knob. SOLUTION: The operation knob 1 is arranged rotatably on a side part of a steering column 101 for mounting an ignition switch, and includes a pair of operation faces 10b, 11b for orienting directions opposite to each other. As for the pair of operation faces 10b, 11b, the operation face 10b on a closer side to an operator position is formed in a concave surface, and the operation face 11b on a distant side from the operator position is formed in a projected surface.
