A power tool includes a power tool main body (1) and a battery pack (2) detachably attached to the power tool main body, the battery pack having at least two engaging portions (4,4',4'') to be mechanically coupled to the power tool main body and the power tool main body having engaged portions (5,5',5'') respectively corresponding to the engaging portions of the battery pack respectively. Each of the engaging portions of the battery pack includes an insertion restricting portion (4a,4a',4a'') and an attachment securing portion (4b,4b',4b'') for allowing its corresponding engaged portion to be inserted only in a direction of pressing the attaching portion of the battery pack against the attached portion of the power tool main body, each of the attachment securing portions being coupled to its corresponding engaged portion. At least one of said at least two engaging portions further has a hook engaging portion (12a) which is selectively secured with an engaged portion moved from its corresponding insertion restricting portion to its corresponding attachment securing portion. |
