PROBLEM TO BE SOLVED: To suppress an increase in the load of an oil pump due to the residence of lubricating oil in a crank chamber.SOLUTION: An inside-shaft oil discharge path (46) includes a main oil discharge path (46a) extending in a driving shaft (40) in the axial direction, and an oil suction path (46b) whose inflow end opens to a crank chamber (55) and whose outflow end communicates with the main oil discharge path (46a). A housing (50) is formed with an auxiliary passage (90) whose inflow end opens to the crank chamber (55) and whose outflow end opens to a lower space (25) of the housing (50). The inflow end of the auxiliary passage (90) is located above the inflow end of the oil suction path (46b).SELECTED DRAWING: Figure 1 |
