    摘要： A lubrication mechanism for a vehicle drive-force transmitting apparatus including; first and second gears meshing with each other in a meshing region; and a casing storing therein the first and second gears. The lubrication mechanism includes a gutter that extends from an inner wall surface such that oil is received in the gutter and is then dropped from an end of the gutter. The gutter includes a flow-direction changing rib with which the received oil is to be collided whereby a flow direction of the received oil is changed to a direction toward the end of the gutter. The end of the gutter is located on upper side of the meshing region, between first and second vertical planes containing respective first and second axes about which the first and second gears to be rotated, and is located between opposite ends of the meshing region.

    摘要： A power transmission unit for preventing malfunction and deterioration in durability of a locking device arranged in a housing by preventing the ingress of foreign matters into the locking device. In the power transmission unit, a one-way brake 10 for selectively stopping a rotation of an output shaft 1a of an engine 1 is disposed between the housing 11 of a transmission mechanism and an engine block 1b. A fixed member 10a is fixed to the housing 11 or to the engine block 1b, and a movable member 10b is attached to the output shaft 1a. A through hole 21 is formed on the housing at a vertically lowest portion and axially outside of a region where the one-way brake 10 is situated, so as to provide a communication between an inner space and an outer space of the housing 11.

    摘要： A driving apparatus of the present disclosure includes an electric motor including a stator and a rotor, a case accommodating the electric motor and mounted on a vehicle so as to partially overlap a side member as viewed from a vehicle width direction, a drive shaft connected to a wheel, a plurality of radial ribs respectively projecting in the vehicle width direction and extending radially, and a connecting rib projecting in the vehicle width direction and joining with center side ends of the plurality of radial ribs. At least part of the plurality of radial ribs reach a first region of the case that overlaps the side member and does not overlap with the wheel as viewed from the vehicle width direction. The driving apparatus improves strength of the case that accommodates the electric motor and is mounted on the vehicle.

    摘要： An installation structure of a one-way clutch in which torque transmission is limited to one direction includes a flywheel, first and second rotary structures, housing and stopper plates, and a rivet. The first rotary structure is arranged coaxially with the flywheel while connected to an engine block. The second rotary structure is arranged coaxially with the first rotary structure while connected to the flywheel. The housing plate is disposed between the flywheel and the first and second rotary structures and arranged coaxially while connected to the second rotary structure. The stopper plate is attached to the second rotary structure to hold first rotary structure with the housing plate. The rivet fastens the stopper plate, the second rotary structure, and the housing plate. A first clearance between one face of the flywheel and a top face of a head of the rivet is narrower than a thickness of the stopper plate.
