PROBLEM TO BE SOLVED: To prevent excessive change of a space between a grip and an operation lever to an unexpected level by a rider in the operation lever for a handlebar vehicle with a grip adjusting mechanism. SOLUTION: A turn regulating means 27 is composed of a fixed protrusion piece 12i on a lever main body 12 and a movable protrusion piece 23g on a seat plate 23d. When an adjuster pin 23 turns in a pin hole 22, the movable protrusion piece 23g abuts on the fixed protrusion piece 12i at one end or the other end thereof to regulate the turn of the adjuster pin 23 within one turn. At abutting of the movable protrusion 23g on the one end of the fixed protrusion piece 12i, a cam face 23f-1 which has a longest distance from a center axle of the adjuster pin 23 is allowed to face abut on a cam abutting face 13d on a knocker 13, and at abutting of the movable protrusion 23g with the other end of the fixed protrusion piece 12i, a cam face 23f-5 which has a shortest distance from the center axle of the adjuster pin 23 is allowed to abut on the cam abutting face 13d of the knocker 13. Thus, the cam face 23f-1 for the maximum grip and the cam face 23f-5 for the minimum grip which are adjacently located do not abut on the cam abutting face 13d successively.
