Abstract
A driver drill may include: a motor; an output part provided forward of the motor and driven by the motor; a speed reduction mechanism disposed between the motor and the output part; a motor bracket disposed between the motor and the speed reduction mechanism; a housing that houses the motor and the motor bracket; an element provided above the motor or the speed reduction mechanism; and a lead wire connected to the element and extending more downward than the motor or the speed reduction mechanism. The lead wire may be sandwiched between the housing and the motor bracket.
