Abstract
Engine starting apparatus comprising a one way clutch. A first oil seal is located on the outer side of a second oil seal in the radial direction of a ring gear. Upon starting of an engine, the time that the first oil seal is slid on the ring gear is short, and after the start of the engine, the first oil seal is not slid on the ring gear. The second oil seal is located on the inner side of the first oil seal in the radial direction of the ring gear. Therefore, the second oil seal hardly deteriorates even if slid on a flywheel at high speed after the start of the engine. By locating the first and second oil seals at different positions in the radial direction of the ring gear, it is possible to improve the startability and the lifetime of a starting apparatus. At least one oil seal has a taper shape in order to generate a thrust force which forces the ring gear away from the flywheel.
