A starter device for an internal combustion engine comprises an output shaft driven by a motor, and a hollow cylindrical assembly disposed coaxially around and axially slidably on the output shaft, which assembly includes a hollow shaft splined to the output shaft, and a hollow cylinder disposed at the front side of the hollow shaft and coupled thereto through an overrunning clutch which transmits a rotational force in one rotational direction. Integrally formed at the front end of the hollow cylinder is a pinion which is placed into driving engagement with a ring gear of the associated engine when the axially slidable assembly is slid to a front position by a shift lever which urges the clutch to move in the axial direction. According to one aspect of the present invention, an annular sealing member is interposed between the hollow cylinder and the output shaft at an axial position in front of the sleeve bearing which rotatably supports the hollow shaft around the output shaft. According to another aspect, the outer circumferential surface of the output shaft is provided with an organic coating, which is formed of a resin such as a fluorocarbon resin or an epoxy resin, along an axial length which is situated in front of the sleeve bearing of the hollow cylinder when the hollow cylinder is at the front position. The resin-coated portion of the output shaft includes at least the portion which projects from the front end of the hollow cylinder when the hollow cylinder is at the rear position.
