A steering wheel shaft to which a steering wheel is attached, a torque detection means for detecting torque applied to the steering wheel, and a steering mechanism for steering steering wheels in response to steering of the steering wheel. an electric motor that transmits output to the steering mechanism via a ball screw mechanism to drive the steering mechanism; a holding means for holding the ball screw mechanism and the electric motor; and a fixing section for holding the holding means via a cross shaft joint. an electric power steering device comprising: a connecting means connected to the electric power steering device; 2. The ball screw mechanism includes a male screw member having a spiral groove connected to the steering mechanism at one end, and a female screw member having a spiral groove corresponding to the male screw member and rotatably held by a holding means. A utility model comprising a large number of balls disposed between a male threaded member and a female threaded member, and wherein the holding means is connected to a fixed part at the other end of the male threaded member that is not connected to the steering mechanism. An electric power steering device according to claim 1. 3. Claims for registration of a utility model, characterized in that the electric motor transmits power to the female threaded member of the ball screw mechanism via a gear mechanism, and is fixed to the holding means so as to have an axis parallel to the male threaded member. The electric power steering device according to item 2. 4. The cross-shaft joint comprises: a first yoke member fixed to the end of the holding means; a second yoke member fixed to the fixed part; and a cross-shaft member disposed between both yoke members. An electric power steering device according to any one of claims 1 to 3, characterized in that it is a utility model. 5. The electric power steering device according to claim 4, wherein the first yoke member and the cross shaft member are connected and fixed by a pin passing through both members. 6. The electric power steering device according to claim 4, wherein the second yoke member and the cross shaft member are connected and fixed by a pin passing through both members.
