Abstract
A driving tool has a main motor, a sub-motor, and a fan. The main motor serves as a driving source to generate electric power to move a driver and is accommodated in a main body housing. The sub-motor is driven independently from the main motor and accommodated in the main body housing. The fan is mounted on an output shaft of a sub-motor.
