At the upper side of the revolving frame equipped with a reduction gear 12 on the (3A), and to place an electric motor 22 having an electric motor shaft 27 on the upper side of the speed reducer 12, and electric motor 22, the hydraulic motor shaft the arrangement (41) the hydraulic motor (34) having a. In the lid portion (23B) of the electric motor casing 23 to form a shaft insertion hole (23E) which is inserted through the upper side of the electric motor shaft 27. The female spline portion (27B) provided on the upper end of the electric motor shaft 27, is spline-coupled with the number of the spline portion (41A) provided on the lower end of the hydraulic motor shaft 41. Inserting the shaft installation hole (23E) and the bearing (28) between the electric motor shaft 27, also along with, located on the upper side of the bearing 28 to install the pressure seal (43). As a result, by using the drain oil leaked from the hydraulic motor 34, the spline coupled portion constant lubrication of the female spline portion (27B) and the number of the spline portion (41A).
