    Abstract: A vehicular power transmitting system including a power transmitting member, an oil pump, and an oil piping assembly, and the oil piping assembly includes an oil piping body having an oil inlet and fixed, and a branch pipe. The branch pipe has a width direction parallel to a longitudinal direction of the oil piping body, and includes proximal and distal end portions. The proximal end portion is connected to the oil piping body, and the distal end portion has a delivery nozzle from which the oil is delivered toward the lubricated portion. The branch pipe has an opening formed in the proximal end portion, for communication of the branch pipe with the oil piping body, the opening having a dimension in a width direction of the branch pipe, which dimension is larger than a dimension of the distal end portion in the width direction of the branch pipe.

    Abstract: A vehicle drive-force transmitting apparatus including: a casing; a drive-force transmitting mechanism disposed in the casing; and first and second oil pumps configured to suck, through respective inlet ports thereof, oil stored in a bottom portion of a casing, such that the drive-force transmitting mechanism is lubricated by the oil pumped up by the first and second oil pumps. The casing is provided with a drain hole through which the oil stored in the bottom portion of the casing is to be discharged to an exterior of the casing. A position of opening of the inlet port of the first oil pump is lower than a position of a lower end of the drain hole, and a position of opening of the inlet port of the second oil pump is higher than the position of the lower end of the drain hole.

    Abstract: The technology disclosed in the present specification is embodied as a support device for supporting maintenance on an apparatus including an expendable component. The support device includes at least one computer. The at least one computer executes: a process of acquiring an index indicative of a consumption level of the expendable component; a process of, at a time point when the index indicative the consumption level reaches a predetermined threshold, specifying a necessary period of time required for replacement of the expendable component at the time point; and a process of restricting an operation of the apparatus when a remaining period of time of the expendable component, the remaining period of time being associated with the threshold, is shorter than the necessary period of time required for the replacement.

    Abstract: A control apparatus for a hybrid vehicle drive system including: a differential device provided with rotary elements respectively connected to an engine, first and second electric motors and an output rotary member; a brake for selectively fixing the rotary element connected to the first electric motor, to a stationary member; and a parking-lock mechanism preventing a rotary motion of a parking-lock gear connected to the output rotary member, when a manually-operated shifting device is operated to a parking-lock position. The control apparatus includes an engine starting control-portion configured to start the engine in a starting-mode wherein an operating speed of the engine is raised with a torque generated by the second electric motor in an engaged state of the brake, where the engine is required to be started while the vehicle has been held at rest and the rotary motion of the parking-lock gear is prevented by the parking-lock mechanism.
