圧タイマのオイルシール装置。Preventing hydraulic oil leaking from the hydraulic piston of a hydraulic timer that adjusts the advance angle of a camshaft of a fuel injection pump by the hydraulic piston from flowing out from a joint between the injection pump and the hydraulic timer. The oil seal device is provided in a hydraulic timer for the purpose of providing an annular wall concentric with the camshaft at the end of the injection pump on the hydraulic timer side, and an oil seal rubber is attached to the inner circumferential surface of the annular wall. A concentric annular wall facing the inner circumferential surface of the annular wall is provided at the injection pump side end of the rotating cover of the timer, and a wear ring is fixed to the outer circumferential surface of the timer so as to be in sliding contact with the oil seal rubber in an oil-tight manner. An oil seal device for a hydraulic timer featuring:
