A power delivering axis of a standard mechanical interface apparatus is provided to reduce an overload effect in a power delivering process by forming power delivering projections and power delivering grooves thereto. A driving unit(260) receives power from a motor. A driven unit(250) receives the power from the driving unit and delivers the power to a rotary member. A plurality of power delivering projections(251,252) and a plurality of power delivering grooves(261,262) are formed at the driving unit and the driven unit in order to delivery the power from the driving unit to the driven unit. The power delivering projections are separated from the power delivering grooves in order to interrupt the power delivered from the driving unit to the driven unit in an overload state.
