Abstract: An impact tool includes a housing, an impact mechanism unit, a motor, and a dust collection fan. The housing is configured to mount a dust collection attachment. The impact mechanism unit is disposed inside the housing. The impact mechanism unit has a front end to which a tool bit is mounted and an impact element that reciprocates. The impact mechanism unit is configured to impact the tool bit by the impact element. The motor is disposed such that a rotation shaft of the motor intersects with an impact axis direction of the impact mechanism unit inside the housing. The dust collection fan is disposed on the rotation shaft. The dust collection fan is disposed below the motor.
