A grease filling method for a ball screw device includes the steps of covering an outer periphery of a screw shaft protruding from one end portion of a nut with a covering member, supplying grease to a portion between a nut inner peripheral surface on one end portion side of the nut and the screw shaft, inserting the protruding screw shaft into a nut inner side while being covered with the covering member, bringing a tip of the covering member in an insertion direction closer to an end portion of an infinite circulation path on the one end portion side of the nut, and sending the grease supplied to the nut inner side to a region of the infinite circulation path, pulling out the covering member together with the screw shaft from the one end portion of the nut, and taking out the covering member from the screw shaft.
