Abstract:
[Problem] To provide an electric tool that, without increasing the number of components, can suppress a fan that cools a motor housed in a housing from being damaged by foreign objects. [Solution] The present invention is an impact driver (1) in which a wind window (30) that interconnects the inside and outside of a housing at the outside of a centrifugal fan is formed at the housing (2), which houses: the motor (M); the centrifugal fan (F), which cools the motor and is attached to the output shaft (14) of the motor; and an annular wind collection member (33) that is disposed between the motor and the centrifugal fan and that gathers cooling air resulting from the centrifugal fan. A wall body (34) positioned to the inside of the wind window is provided to the wind collection member.
