The invention discloses a starting shaft oil leakage prevention structure of a single-cylinder diesel. The starting shaft oil leakage prevention structure comprises a crankshaft box, a gear chamber arranged in the crankshaft box, a starting shaft arranged in the gear chamber and a gear chamber cover arranged at one end of the crankshaft box. One end of the starting shaft extends out of the gear chamber cover to be connected with a fly wheel. An oval-ring-shaped sealing cavity is formed in the gear chamber cover. An oval-ring-shaped oil seal is arranged in the oval-ring-shaped sealing cavity. The oval-ring-shaped oil seal comprises a first oil blocking ring abutting against the inner side of the starting shaft and a second oil blocking ring abutting against the outer side of the starting shaft. A conical oil outlet hole is formed in the lower end of the part, between the first oil blocking ring and the second oil blocking ring, of the oval-ring-shaped oil seal, and an air inlet hole is formed in the upper end of the part, between the first oil blocking ring and the second oil blocking ring, of the oval-ring-shaped oil seal. An air inlet channel is formed in the crankshaft box.
