Oil passage structure for power transmission device

An oil passage structure for a power transmission device, the oil passage structure comprising:

• a case provided to accommodate the power transmission device;
• a baffle plate attached to an inner wall of the case;
• an oil pump;
• and
• a supply oil passage through which oil is pumped from the oil pump to an oil supply destination via the baffle plate, the baffle plate having a plate oil passage, a supply port and a discharge port, the plate oil passage being an oil passage that constitutes a portion of the supply oil passage, the supply port being configured to allow the oil discharged from the oil pump to flow into the plate oil passage through the supply port, and the discharge port being configured to allow the oil supplied to the oil supply destination, to be discharged from the plate oil passage through the discharge port, wherein:
• the power transmission device includes a transmission, a counter gear mechanism, and a differential gear mechanism;
• the oil pump is a mechanical oil pump which is driven by engine torque transmitted to the mechanical oil pump via the power transmission device;
• and
• the plate oil passage is provided so as to pass between a rotary shaft of the transmission and a rotary shaft of the differential gear mechanism.

• the baffle plate has a tubular part, and a flange part that extends radially outwardly from the tubular part;
• the plate oil passage extends in a circumferential direction of the baffle plate;
• and
• the discharge port is provided at a position, which is different in the circumferential direction of the baffle plate from a position at which the supply port is provided, such that oil is supplied to the oil supply destination.
