Embodiment Construction

[0185] Embodiments will be described below with reference to the drawings. In the following descriptions, the up-down, front-back, and left-right directions are the same as figure 1 and 2 Corresponds to the directions shown in .

[0186] figure 1 An impact tool 1 according to one embodiment is illustrated. The impact tool 1 drives the impact mechanism 40 with the rechargeable battery pack 30 as a power source and the electric motor 3 as a driving source, and provides rotation and impact to an anvil 46 as an output shaft to transmit continuous torque or intermittent impact power to the tip A tool (not shown), such as a drill bit, is driven to perform operations such as screw tightening or bolt tightening.

[0187] The motor 3 is a brushless DC motor, and is accommodated in a tubular trunk portion 6a of a housing 6 having a substantially T-shape when viewed from the side. The housing 6 is detachable into two substantially symmetrical right and left parts, and the right and ...
