PROBLEM TO BE SOLVED: To make it possible to open/close a door regardless of an engine being actuated as well as make installation on a vehicle be easy.SOLUTION: A motor unit 2 includes: a door opening/closing motor 8; a feed screw mechanism 9; a transmission gear part 10; and a release lever 11 for releasing a holding state of a door catch. The feed screw mechanism 9 includes: a case 15; a screw shaft 16 accommodated inside the case 15; a nut 17 that is coupled with the screw shaft 16 and moves in the shaft direction of the screw shaft 16 by rotation of the screw shaft 16; a cylindrical transmission rod 18 that is accommodated inside the case 15 so as to be capable of sliding in the shaft direction of the screw shaft 16 and encloses the screw shaft 16; a compression spring 19 existing between the nut 17 and the transmission rod 18; and a cage body 20 that surrounds the nut 17, the transmission rod 18's nut 17 side end, and the compression spring 19.SELECTED DRAWING: Figure 4 |
