Abstract:
A propeller shaft for torque transmission, comprising:first and second torque transmission members in opposition to each other;a torsion bar connecting the first torque transmission member and the second torque transmission member, the torsion bar rotating integrally with the first and second torque transmission members so as to perform a function of torque transmission;a viscous fluid damper including first and second relative rotation members and a viscous fluid, the first and second relative rotation members being individually connected to the first and second torque transmission members, respectively, the first relative rotation member rotating integrally with the first torque transmission member, the second relative rotation member rotating integrally with the second torque transmission member, with a viscous fluid between the relative rotation members to transmit force parallel to the torsion bar, so that a shearing stress of the viscous fluid generated between the relative rotation members absorbs a vibration in a rotating direction when the torsion bar is twisted and the relative rotation members make a relative rotation; anda stopper for restricting a maximum torsion angle of the torsion bar, wherein the stopper has a first abutting portion on the first torque transmission member and a second abutting portion on the second relative rotation member, with the abutting portions abutted against each other to prevent the torsion bar from being further twisted when the torsion bar is twisted at the maximum torsion angle.
