PROBLEM TO BE SOLVED: To provide a novel electric driving device having excellent heat radiation characteristics while reducing the appearance shape in size, the weight, and a number of components, and an electric power steering device.SOLUTION: An electric driving device comprises: the prescribed number of screw stopper concave parts 38 that is concaved in an inner radial direction side formed on an outer peripheral surface of an end surface part of an aluminum type metal motor housing 11 on the side opposite to an output part of a rotational axis of an electric motor; and a screw stopper convex part 39 that is projected to the inner radial direction side housed in the screw stopper concave part formed in the outer peripheral surface of a metal cover 12 covering an electronic control part that controls the electric motor. The screw stopper convex part 39 is fixed to the screw stopper concave part 38 with a metal fixing screw 37 toward an inner side from a radial direction while housing the screw stopper convex part 39 in the screw stopper concave part 38 in a state where a head part 37H of the fixing screw 37 is not projected from an external surface of the metal cover 12.SELECTED DRAWING: Figure 11

    【課題】、外観形状を小さくし、また重量及び部品点数を低減すると共に、良好な放熱特性を備えた新規な電動駆動装置及び電動パワーステアリング装置を提供することにある。【解決手段】電動モータの回転軸の出力部とは反対側のアルミ系金属製のモータハウジング11の端面部の外周面に形成された径方向内側に凹む所定数のねじ止め凹部38と、電動モータを制御する電子制御部を覆う金属カバー12の外周面に形成されたねじ止め凹部に収納される径方向内側に突出するねじ止め凸部39とを備え、ねじ止め凹部38にねじ止め凸部39を収納して径方向から内側に向けて金属製の固定ねじ37によって、固定ねじ37の頭部37Hが金属カバー12の外表面から突出しない状態でねじ止め凸部39をねじ止め凹部38に固定する。【選択図】図11
