Abstract: A power tool (1; 101) includes: a motor (6; 106) having a stator (61) and a rotor (63), which is rotatable relative to the stator; an output part (8; 108) disposed more forward than the motor and configured to be rotated by the motor; a motor-housing part (21; 121), which houses the motor; a grip part (22; 122) disposed downward of the motor-housing part; a battery-holding part (23; 123) disposed downward of the grip part; and a COB light (50) disposed on the battery-holding part.

Abstract: An electric work machine avoids use of more lead wires. The electric work machine includes an operation unit operable in an operation mode of at least three operation modes, an operable member movable to switch the operation mode, a plurality of mode sensors located in a direction of movement of the operable member to detect the operable member and being equal in number to or fewer than the at least three operation modes, a mode sensor board on which the plurality of mode sensors are mounted and including an output terminal connected to the plurality of mode sensors, and a controller board connected to the output terminal with an output lead wire to determine the operation mode based on an output signal output from the output terminal.

Abstract: A fastening tool includes a motor, an anvil, a pin-gripping part, a magnet having the north pole and the south pole aligned in a front-rear direction and configured to move integrally with the pin-gripping part in the front-rear direction, a first magnetic sensor having a first sensing surface, a second magnetic sensor having a second sensing surface and disposed rearward of the first magnetic sensor, and a control device configured to move the pin-gripping part rearward based on a detection result of the second magnetic sensor and to move the pin-gripping part forward based on a detection result of the first magnetic sensor. The first and second magnetic sensors are unipolar detection type sensors configured to detect a same specified pole of the magnet. Orientations of the first sensing surface and the second sensing surface relative to a movement axis of the magnet are opposite to each other.
