PROBLEM TO BE SOLVED: To provide an wilkey for handle operation which can facilitate not only the manual rotary operation of a handle but also improve the operability regardless of an obstacle existing around the handle, and furthermore, which is excellent in portability, since it is compact and lightweight, and does not damage the handle since it is possible to regulate a force adjustment. SOLUTION: The wilkey 1 for rotating the handle 50 having a ring-shaped section 53 fixed through a rib 52 to a rotary shaft 51 is equipped with a grip 2 having a greater diameter than the ring-shaped section and a plurality of fitting projections 10 which are projectingly arranged on the front faces of the grip corresponding to an engaging section 54 formed between the rib and the ring-shaped section at a position where the fitting projections 10 can be fitted into a bore or a recess.
