Propeller shaft

A propeller shaft for transmitting driving force of a vehicle, the propeller shaft comprising:

• a vehicle mounting member that serves for mounting to the vehicle, and includes a mounting part structured to be mounted to the vehicle and a supported part supported by the mounting part;
• and
• a first shaft unit that is supported by the vehicle via the vehicle mounting member, and includes a sleeve yoke, a stub shaft, and a tube,
• wherein:
• the sleeve yoke is structured to be connected to an output shaft of a transmission of the vehicle, and receive driving force of the vehicle via the output shaft;
• the stub shaft is disposed oppositely to the sleeve yoke in a direction of a rotational axis of the first shaft unit, and is covered by the supported part of the vehicle mounting member;
• the tube connects the sleeve yoke and the stub shaft;
• and
• the stub shaft includes a weakest part structured to be less in torsional strength than a remaining part of the first shaft unit and formed at a position at which the stub shaft overlaps with the vehicle mounting member in the direction of the rotational axis.
