Steering device

A steering device comprising:

• an inner shaft rotatable around an axial line;
• and
• an outer shaft partially covering the inner shaft and rotatable together with the inner shaft;
• wherein the inner shaft and the outer shaft are provided so as to be relatively movable to each other along the axial line;
• wherein the inner shaft comprises:
• an axial member provided on the axial line;
• a first abutting member provided on an outer circumference of the axial member;
• and
• a second abutting member provided on the outer circumference of the axial member adjacent to the first member, and having a different hardness from a hardness of the first abutting member;
• wherein an abutting member support of the axial member where the first abutting member and the second abutting member are provided is formed in a shape other than a circular shape with reference to a vertical cross-section to the axial line;
• and
• wherein the outer shaft comprises a torque transmitting member which abuts only either the first abutting member or the second abutting member and which is capable of transmitting torque only with the abutting member that is abutting the torque transmitting member.
