1. An electric tool comprising:
a motor housing including motor housing halves joined to each other at a joint plane extending substantially through a motor axis, a motor serving as a drive source and assembled as a motor assembly received within the motor housing; wherein the motor includes a stator and a rotor, the stator being configured to be fixed within the motor housing, the rotor being configured to be rotatable about the motor axis relative to the stator; wherein a part of a flow passage of cooling air for cooling the motor is defined in the motor and extends in a direction substantially parallel to the motor axis; and a baffle configured as a separate member from the motor housing and located at a position proximal to an end portion of the stator positioned on a downstream side with respect to the flow of the cooling air; wherein the baffle has a width in an axial direction of the motor axis and is configured to restrict a flow area of the cooling air flowing through the baffle in the axial direction; wherein the baffle is mounted to an inner circumferential wall of the motor housing; wherein at least a part of the width of the baffle is positioned within a range of a length with respect to the axial direction of the end portion of the stator and wherein the baffle has an outer circumferential surface having a recess formed therein, and the motor housing has an inner circumferential surface having a rib configured to engage the recess, so that the baffle is positioned relative to the motor housing with respect to the axial direction. |
