PROBLEM TO BE SOLVED: To provide a power tool which is configured so as to perform operations from a manual operation by a worker to completion of a preset operation as one cycle using a motor as a driving source, in which heat generated by the motor can be efficiently radiated.SOLUTION: A nailing machine 1 includes a trigger 131, a motor 2, a driving mechanism 3, a controller 4, a crank housing 320 and a heat transmission member 5. The controller 4 starts driving of the motor 2 in response to a pressing operation to the trigger 131 by a worker and stops the driving of the motor 2 when the driving mechanism 3 completes one cycle of a nail driving operation. The heat transmission member 5 is configured so as to form a heat transmission path different from a power transmission path ranging from the motor 2 to the driving mechanism 3, and release the heat generated by the motor 2 to the metal crank housing 320.SELECTED DRAWING: Figure 2 【課題】モータを駆動源として、作業者による手動操作手動から予め設定された動作の完了までを１サイクルとして遂行するように構成された電動工具において、モータで発生した熱をより効率的に放熱することが可能な技術を提供する。【解決手段】釘打ち機１は、トリガ１３１、モータ２、駆動機構３、コントローラ４、クランクハウジング３２０、伝熱部材５を備える。コントローラ４は、作業者のトリガ１３１に対する押圧操作に応じてモータ２の駆動を開始し、且つ、駆動機構３が１サイクルの釘の打込み動作を完了すると、モータ２の駆動を停止する。伝熱部材５は、モータ２から駆動機構３へ至る動力伝達経路とは異なる伝熱経路を形成し、モータ２で発生した熱を、金属製のクランクハウジング３２０へ逃がすように構成されている。【選択図】 図２
