It is an object of the present invention to provide a technique for making the effective use of cooling air for a motor (121) within a power tool (101) in order to rationalize the structure of the power tool (101). The representative power tool (101) may comprise a tool bit case (113), a tool bit (129), a drive motor (121) and a cooling air guiding member (137). The tool bit (129) is provided within the tool bit case (113) and performs a predetermined operation on a workpiece. The drive motor (121) drives the tool bit (129). The cooling air guiding member (137) guides cooling air for cooling the drive motor (121) to a work area of the workpiece to be worked on with the tool bit (129), when the cooling air is discharged into the tool bit case (113). By such construction, the representative power tool (101) can have a rationalized structure whereby cooling air for cooling the drive motor (121) of the power tool (101) can also be utilized to clean the work area of the power tool (101). <IMAGE> |
