A draft key retainer (3) for supporting the draft key is installed underneath the head of the draft gear yoke body (1). The shape of the upper surface of a supporting part of the draft key retainer (3) corresponds with a lower surface of the draft - - - - - - - -- - - - -key to form surface-contact between the two surfaces.
