Ahammerdrill (101) comprises a main body (103) which houses a driving motor (110) having a brush (170) and a brush holder unit (171) which holds the brush (170) and switches a position of the brush (170), and a main handle (109) which is movable to the main body (103). Further, a coil spring (160) which biases the handle (109) is provided. In a state that the coil spring (160) biases the handle (109), the handle (109) is moved against the main body (103) in a longitudinal direction of a hammer bit (119) and vibration transmission from the main body (103) to the handle (109) is prevented. Further, interference of a lever (175) of the brush holder unit (171) and the handle (109) is prevented by a part (165a, 165b) of an opening (165) formed on the handle (109). |
