    • PROBLEM TO BE SOLVED: To provide technology capable of more securely detecting excessive reaction torque acting on a tool body in a power tool for carrying out processing work by a tip tool that is rotated. SOLUTION: A hand-held power tool has a tool body 103 and a motor 111 stored in the tool body 103 and applies predetermined processing work to a workpiece by the tip tool 119 that is rotated with the motor 111. The power tool has a first sensor 151 for detecting the torque state of the tip tool 119; a second sensor 159 for detecting the motion state of the tool body 103; and a torque interruption mechanism 134 for interrupting torque transmission between the motor 111 and the tip tool 119 on condition that the first sensor 151 and the second sensor 159 respectively detect preset thresholds of the first sensor 151 and the second sensor 159.

    • PROBLEM TO BE SOLVED: To technologically easily control a locking switch for a motor switch in a guide clip. SOLUTION: This rotary impact hand tool device is provided with: the motor switch 5 for controlling a motor; the guide clip 4 insulating vibration from an impact tool device 2 for generating vibration; the locking switch 7 movable in a switching area X for locking the motor switch 5; and an operation mode switching switch 3 in the impact tool device 2 for moving a switching rod 9. The switching rod 9 has a stopper 10 projecting to the switching area X in a rotary operation mode. The locking switch 7 for locking is suitably constituted so that a hook 13 engages with a cutout 15 arranged in the motor switch for switch closing operation by elastically deforming a flexible plate spring 12 fastening one end part and forming the other loose end in a hook 13 shape.
