[Problem] To obtain suitable durability and also achieve increased compactness. [Solution] A screw driver (1) comprising a housing (2), a brushless motor (22) with a stator (23) fixed to the housing (2) and a rotor (24) that is rotatable with respect to the stator (23), a second spindle (57) capable of holding a bit, a clutch (cam (60), cam section (63)) disposed between the rotor (24) and the second spindle (57), and a battery pack (12) fixed to the lower section of the housing (2). The brushless motor (22) is disposed below the clutch. |
