<P>PROBLEM TO BE SOLVED: To provide a valve operation tool that can be widely used for valve handles having different shapes and allows fine adjustment of applied force and stable distribution of force when engaged with a valve handle, thereby improving safety. Ž<P>SOLUTION: A plurality of cutout portions 13 are provided on the body 11 of the valve operation tool. Projecting portions 14 of the cutout portions 13 are inserted into the penetrating portions 19 of the handle 16, and the body 11 is turned so that the side surfaces of the projecting portions 14 of the cutout portions 13 are brought into contact with the spokes 18 of the valve handle 16. A socket joined to a wrench is attached to a joint hole 12 provided on the top of the body 11, and the body 11 is turned by operating the wrench. This allows fine adjustment of torque.
