PROBLEM TO BE SOLVED: To provide a torque tool such as an immediately usable torque wrench and torque driver by releasing a sleep mode when a worker only holds the torque wrench by hand even in operation of the sleep mode. SOLUTION: This torque wrench has a microcomputer 4 for setting the sleep mode for saving electric power when a measuring signal is not inputted in a predetermined time by arithmetically operating a torque value when inputting a signal for measuring torque caused by fastening of a bolt. The microcomputer 4 releases the sleep mode when a vibration sensor 1 detects the movement of the torque wrench. COPYRIGHT: (C)2005,JPO&NCIPI
