PURPOSE:To make compact a driving element and to make it possible to revolve, raise and lowering a door electrically even if a setting angle varies by providing an electric feeding screw mechanism consisting of a movable section, bearing section and energizing member to a post, and connecting to a swiveling section. CONSTITUTION:A movable section such as a nut N and the like, and a bearing section such as a bolt B, a motor M and others are constrained on a common working axis Y. After that, with the working axis Y of the movable section and bearing section, while elastically energizing each other by a driving member 61 to be inserted inward of the nut N, and an electric feeding screw mechanism D to be interlocked indirectly is connected to a swiveling section K such as a door, supporting arm 21 and others. Then, the radial direction of a driving element is compacted by the insertion of the energizing member 61 inward of the nut N. The free end of the bolt B is held together with the bearing section such as the motor M and the like as a unit by a supporting piece, and the stress distribution of the bolt B is the driving element of an improved axial rising and falling type electric rotary rising and falling door. |
