  • Patent number: 11953084
    Abstract: A drive device protection structure has a rotary electric machine, a gearbox connected the rotary electric machine, an undercover disposed underneath the drive device and a protecting plate provided to the undercover. The rotary electric machine has a rotary electric machine housing that has a rotary electric machine flange. The gearbox has a gearbox housing that has a gearbox flange. The rotary electric machine flange and the gearbox flange are connected together. The rotary electric machine flange and the gearbox flange are formed such that a lower surface of the gearbox flange is positioned lower than a lower surface of the rotary electric machine flange. The protecting plate is formed of a material more rigid than a material of the undercover. The protecting plate is provided beneath connecting part between the rotary electric machine flange and the gearbox flange so as to face the connecting part.

  • Patent number: 9243436
    Abstract: A spring hook structure includes: a torsion coil spring including a coil portion and a first arm and a second arm extending from each side of the coil portion; and a rotation support pin by which a cap is rotatably supported on an exterior case. The rotation support pin is inserted into the coil portion. The first arm is hooked on a first hook surface of the exterior case, and the second arm is hooked on a second hook surface of the cap. At least one of the exterior case and the cap is provided with a regulation wall at a position not interfering with the arm moving along the hook surface due to flexural deformation of the coil portion but interfering with the arm moving along the hook surface due to flexural deformation of the arm.
