A vehicle drive apparatus includes a case main body portion accommodating the speed change mechanism; supply oil passages that are formed in the case main body portion and supply pressure oil to the speed change mechanism; a connection case portion connecting the engine and the case main body portion; a mechanical oil pump positioned in a connection region between the case main body portion and the connection case portion and having an inlet oil passage and an outlet oil passage which are connected to the supply oil passage; an electric oil pump capable of supplying pressure oil to the supply oil passages in parallel with the mechanical oil pump; and connection oil passages that are provided in the connection case portion and allow an inlet oil passage and an outlet oil passage of the electric oil pump to communicate with the supply oil passages.

Vehicle drive apparatus

A hydraulic control device includes a valve body having oil passages, a solenoid valve incorporated in the valve body, an oil pan that is disposed below the valve body and that accumulates hydraulic oil, and a strainer which, as well as being disposed between the valve body and the oil pan, has a filtering medium which filters the hydraulic oil suctioned from the oil pan. The strainer is fixed to the oil pan by a magnetic force of at least one magnet.

Hydraulic control device

A vehicle power transmission device including an accumulation portion which accumulates lubricating oil, a pressure pump driven to pump the lubricating oil accumulated in the accumulation portion to the transmission as hydraulic oil, a scooping gear which scoops up the lubricating oil accumulated in the accumulation portion while rotating, a reception and guide portion receiving the lubricating oil scooped up by the scooping gear and guiding it to a predetermined lubrication target, and a leaked hydraulic oil guide portion guiding leaked hydraulic oil, leaked when the hydraulic oil is pumped from the pressure pump, to the reception and guide portion.
