Abstract (en)

[origin: EP4190494A1] An object of the present disclosure is to contribute to reducing the dimension of a tool along the axis of a drive shaft thereof. An impact rotary tool (1) includes a drive shaft (4), a speed reducer mechanism (5), an output shaft (13), a hammer (11), a spring (12), and a bearing member (6). The speed reducer mechanism (5) transmits rotational force of a shaft of a motor (31) to the drive shaft (4). The output shaft (13) receives rotational force from the drive shaft (4) and transmits the rotational force to a tip tool (B1). The hammer (11) is supported rotatably by the drive shaft (4) and strikes the output shaft (13). The spring (12) biases the hammer (11) toward the output shaft (13). The bearing member (6) supports the drive shaft (4) rotatably. The bearing member (6) is disposed closer to the output shaft (13) than the speed reducer mechanism (5) is along an axis (A1) of the drive shaft (4).
