PROBLEM TO BE SOLVED: To provide a torque tool used for tightening or loosening a connecting implement. SOLUTION: The torque tool is equipped with a driving element engageable with a rotatable part of the connecting implement and a power source 11 acting on the driving element. The rotatable part of the connecting implement is rotated by one stroke to separate from the driving element by making the power source 11 act on the driving element. Then, the rotatable part of the connecting implement is rotated by one stroke by approaching the driving element and acting on it again. COPYRIGHT: (C)2008,JPO&INPIT
