PURPOSE:To make it possible to remove from oil fine dust which is detrimental to a hydraulic clutch for motor cars or the like, by disposing, between the hydraulic clutch and a clutch valve, a filter for removing fine dust. CONSTITUTION:A line filter 45 is disposed in an oil passage 44 through which oil is fed to a hydraulic clutch 14 from a mission casing 10 through a main filter 42, a pump 40, a pressure control block 43, and a clutch valve 17. This line filter 45 is fitted in a feed port 19a in the mission casing 10. The oil enters into this filter 45 from the oil passage 44 passes through a fine mesh element 54 such as, for example, folded filter paper having a mesh finer than that of the main filter 42, and therefore, fine dust in the oil is removed from the oil before the oil is fed to the hydraulic clutch 4 through an oil passage 19. Thus, fine dust which is detrimental to the clutch may be effectively removed from the oil. |
