Abstract
An attachment includes a planetary reducer, a reaction force receiving member, and a universal joint. The planetary reducer has a first output shaft and a second output shaft connectable to a socket. The reaction force receiving member is connected to the first output shaft and has an arm part for contact with an external contact object. The universal joint has an input-side end part connectable to a final output shaft of a fastening tool and an output-side end part connected to the planetary reducer. The reaction force receiving member is configured to rotate integrally with the first output shaft in a direction opposite to the second output shaft by a reaction force caused by rotation of the socket. The universal joint is configured to transmit the torque inputted from the final output shaft via the input-side end part, to the planetary reducer via the output-side end part.
