Abstract
A centrifugal type oil filter for the engine, which is simple in construction, comprising a crank shaft of the engine, a clutch having a driving plate mounted on the crank shaft so that it may be rotated with the crank shaft, and oil passage axially formed within the crank shaft, and a bowl-shaped filter cap secured to one side of the driving plate to interiorly define, in cooperation with the side of the driving plate, a centrifugal separating chamber disposed in the midst of the oil passage. The clutch is in the form of a centrifugal clutch comprising clutch shoes radially expandably connected to the driving plate by oscillating links and a clutch drum disposed radially outwardly of the clutch shoes and adapted to be frictionally connected to the clutch shoes when the latter are expanded under centrifugal force. A resilient member is interposed between the clutch shoes and the filter cap to restrain the lateral oscillation of the clutch shoes.
