PROBLEM TO BE SOLVED: To obtain easily a baffle function while maintaining compactification even in a structure in which a motor housing is blocked by a rear cover.SOLUTION: An impact driver 1 includes a motor 12 which comprises a stator 19 and a rotor 20, a tip tool driven by the motor 12, a tubular motor housing 17 in which the motor 12 is housed, a bearing 34 which holds the end part of the rotor 20, and a rear cover 32 which holds the bearing 34 and is connected to the motor housing 17. A convex part 17c is formed at the connecting end part of the motor housing 17, a concave part 32a is formed at the connecting end part of the rear cover 32, and a baffle part 41 which protrudes to the axis side of the motor housing 17 is provided at the connecting end part of the motor housing 17. |
