Claim:
A telescopic shaft constructed by fitting a male shaft and a female shaft to each other so as to be capable of transmitting torque therebetween and moving axially relative to each other, said telescopic shaft comprising: a first torque transferring member interposed via an elastic member between a pair of axis-directional grooves formed respectively on an outer peripheral surface of said male shaft and an inner peripheral surface of said female shaft; and said elastic member including: a transferring-member-side contact portion abutting on said first torque transferring member; a shaft-side contact portion spaced away at a predetermined interval from said transferring-member-side contact portion and abutting on said male shaft or said female shaft; and a biasing portion elastically biasing said transferring-member-side contact portion and said shaft-side contact portion away from each other, wherein a rigidity of said transferring-member-side contact portion is higher than that of said shaft-side contact portion or of said biasing portion.
