Claims

[Scope of utility model registration request]

A tube shaft and a solid shaft with a resin-filled groove formed in the hollow molded part of the tube shaft are fitted and inserted, and a resin-injected extrusion is inserted into the resin-filled groove of the solid shaft at the insertion and overlapping part of the tube shaft and the solid shaft. In an energy absorbing shaft in which a tube shaft and a solid shaft are fixed by a shear pin, the hollow molded portion of the tube shaft and the solid shaft inserted into the hollow molded portion are both formed into polygonal shapes. An energy absorbing shaft, characterized in that a tube shaft and a solid shaft are fitted together, and the tube shaft and the solid shaft are fixed by the shear pin.
