Abstract
A lubrication structure of a transmission includes a gear chamber having an internal space storing lubricating oil, in which chamber a pressure is raised to a prescribed pressure, a gear chamber having an internal space communicating to the internal space through a communicating hole and attaining a pressure lower than the prescribed pressure, and an oil catch tank provided in the internal space at a position directly under the communicating hole and receiving the lubricating oil that flows into the internal space from the internal space through the communicating hole. With such a structure, a lubrication structure for a transmission capable of holding an oil level at a proper level with a simplified structure can be provided.
