PROBLEM TO BE SOLVED: To provide an operation lever capable of connecting a knob and a knob cover exactly, and formed with stoppers. SOLUTION: A pair of the stoppers 18, 20 is formed in the cover knob 14, and groove parts 44, 46 for storing the stoppers 18, 20 are formed in the knob 34. Spacing for end faces 22, 24 of the stoppers 18, 20 is equal to an inside diameter size (diameter size) of a main body inserting hole 16, the end faces 22, 24 of the stoppers 18, 20 contact with an outer circumferential part of a lever main body 12, the stoppers 18, 20 are precluded thereby from being deformed elastically toward a direction approaching each other, and protrusions 28, 32 of corrugated parts 26, 30 are precluded from coming off from recesses 50, 54 of corrugated parts 48, 52. Therefore, the cover knob 14 is connected strongly to the knob 34, and an attaching position is freely changed in every interval of the protrusion 28 of the corrugated part 26 formed in the stoppers 18, 20.
