Abstract:
A propeller shaft is proposed which comprises an inner cylindrical member that has a center through bore into which a shaft is inserted; an outer cylindrical member disposed around the inner cylindrical member; a torque transmitting unit operatively disposed between the inner and outer cylindrical members; a sleeve member coaxially connected to the center through bore of the inner cylindrical member; a boot unit arranged to hermetically close one open side of an interior of the outer cylindrical member; and a positioning mechanism that effects a relative axial positioning between the shaft and the inner cylindrical member when a splined cylindrical outer wall of the shaft is inserted through the sleeve member into a given position of a splined cylindrical inner wall of the center through bore of the inner cylindrical member.
