Abstract: A lubrication structure for a vehicle includes: a first lubrication pipe through which lubricating oil is supplied to a rotary machine disposed in a case; a second lubrication pipe through which lubricating oil is supplied to a bearing member disposed in the case; and an oil pump that supplies lubricating oil to the first and second lubrication pipes. The lubrication structure includes a first oil hole in the case that is connected to the first oil hole, and a second oil hole in the case, lubricating oil flowing into the second oil hole from the second lubrication pipe. A connection portion between the first lubrication pipe and the first oil hole is located above an opening portion of the second oil hole such that at least a part of lubricating oil that has flowed out from the connection portion flows into the second oil hole.

Abstract: A control apparatus for a vehicle includes: a characteristic storage portion configured to store therein torque-characteristic information representing an output torque characteristic as a characteristic of an output torque of an engine of the vehicle, which has appeared in a certain control operation, such that the stored torque-characteristic information is divided into a plurality of groups corresponding to respective refueling points that provide the fuel; and a factor determination portion configured, when the output torque characteristic represented by the torque-characteristic information belonging to one of the plurality of groups and the output torque characteristic represented by the torque-characteristic information belonging to another one of the plurality of groups are different from each other and a characteristic difference therebetween is not smaller than a threshold value, to determine that the characteristic difference is caused by a difference in a property of the fuel.

Abstract: A power transmission device includes a rotor shaft, a gear shaft, and a rattling suppression member. The rattling suppression member is provided between a first shaft end portion and the gear shaft or between a second shaft end portion and the rotor shaft. The first shaft end portion is a portion, protruding to the gear shaft side from one of a pair of first bearings, of the rotor shaft, while the second shaft end portion is a portion, protruding to the rotor shaft side from one of a pair of second bearings, of the gear shaft.
