PROBLEM TO BE SOLVED: To provide a power tool capable of stably attaching a blade unit to a body part.SOLUTION: A power tool 10 is provided with: a body part 11 that houses a motor 12; a blade unit 21 that is detachable from the body part 11 and that has a blade tool 22 operated by receiving a driving force from the motor 12; and a driving connection part M connected by attaching the blade unit 21 to the body part 11 to transmit a driving force of the motor 12 to the blade unit 21. On the body part 11 side, four locking claws 61b are arranged so as to be movable. On the blade unit 21 side, locking parts 71 engageable by the four locking claws 61b are provided. In a top view, assuming a virtual square shape α formed by connecting locking positions P constituted by the four locking claws 61b and the locking parts 71 engageable by the four locking claws 61b through a virtual line, the driving connection part M is positioned inside the virtual square shape α.SELECTED DRAWING: Figure 5 【課題】本体部に対する刃体ユニットの安定した装着状態を得ることのできる電動工具を得る。【解決手段】この電動工具１０は、モータ１２を収納する本体部１１と、本体部１１に着脱可能でありモータ１２からの駆動力を受けて動作する刃体工具２２を有する刃体ユニット２１と、本体部１１への刃体ユニット２１の装着によって連結してモータ１２の駆動力を刃体ユニット２１へ伝達する駆動連結部Ｍと、を備える。本体部１１側には、移動可能に配設された４個の係止爪６１ｂが設けられ、刃体ユニット２１側には、４個の係止爪６１ｂが係止可能な係止部７１が設けられ、上面視において、４個の係止爪６１ｂと、当該４個の係止爪６１ｂが係止可能な係止部７１とのそれぞれで構成される係止位置Ｐを仮想線で結ぶことによって形成される仮想四角形状αを想定したときに、仮想四角形状αの内側に、駆動連結部Ｍが位置するように構成される。【選択図】図５
