    • PROBLEM TO BE SOLVED: To provide a power tool allowing an easy and exact torque adjustment even at a dark place with a simple constitution. SOLUTION: In this driver drill (power tool) 1, a motor 3 and a torque adjusting mechanism 8 are built in a housing 2, and torque transmitted to a driver bit (distal end tool) 7 can be adjusted by rotating a cylindrical torque adjusting dial 10 provided at a distal end of the housing 2. The torque adjusting dial 10 is made of a transparent member, and the whole of the torque adjusting dial 10 is made to emit light by irradiating the torque adjusting dial 10 with light from a light source. A figure showing a torque set value is displayed on an outer peripheral surface of the torque adjusting dial 10. As the light source, a LED (Light Emitting Diode) light 17 is used.
