摘要： A half-shaft assembly includes a first constant velocity (CV) joint, a second CV joint and an axial movement joint connected between the first CV joint and the second CV joint. The axial movement joint includes a first shaft coupled to the first CV joint and a second shaft coupled to the second CV joint, wherein mechanical input received on the first shaft is communicated to the second shaft, and wherein the second shaft slides axially within the first shaft. The axial movement joint further includes an axial boot cover coupled on a first end to the first shaft and on a second end to the second shaft that accommodates axial movement of the first shaft relative to the second shaft. The first constant velocity (CV) joint is coupled to provide torsional input received at an input to the first shaft, the first CV joint having a first CV boot cover. The second CV joint coupled to provide torsional output received from the second shaft to an output, the second CV joint having a second CV boot cover.

摘要： 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.

摘要： A boot band for fixing a boot that is mounted to a constant velocity universal joint is clamped. The boot band and the constant velocity universal joint are aligned in phase with each other in a circumferential direction. An axial position of a clamping portion is thereafter aligned with an axial position of the boot band. Then, the boot band is clamped by the clamping portion.
