Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an electric tool which enables reduction of a length along an axis direction of a motor and improvement of accuracy of a stator and a rotor.SOLUTION: An impact driver 1A which is an electric tool includes a rear housing 11R and a front housing 11F divided in an axial direction along a shaft 20a of a brushless motor 2. A stator 21 of the brushless motor 2 and an internal gear 42 of a speed reducer 4 are supported by the rear housing 11R. The rear housing 11R includes a shaft support part 12B supporting a bearing 24a into which one side of the shaft 20a is inserted. The internal gear 42 includes a shaft support part 42c supporting a bearing 25 into which the other side of the shaft 20a is inserted.SELECTED DRAWING: Figure 1
【課題】モータの軸方向に沿った長さを短くすることが可能で、かつ固定子と回転子の精度を向上させることが可能な電動工具を提供する。【解決手段】電動工具であるインパクトドライバ1Aは、ブラシレスモータ2の軸20aに沿った軸方向に分割される後ハウジング11Rと前ハウジング11Fを備える。ブラシレスモータ2の固定子21と減速機4のインターナルギア42は、後ハウジング11Rに支持される。後ハウジング11Rは、軸20aの一方の側に挿入されるベアリング24aを支持する軸支持部12Bを備え、インターナルギア42は、軸20aの他方の側に挿入されるベアリング25を支持する軸支持部42cを備える。【選択図】図1 |
