Abstract:
The present disclosure provides a transmission device that can increase lubricity of a differential mechanism without using a pump. The present disclosure is a transmission device comprising a differential case and a differential mechanism that is disposed inside the differential case. The differential mechanism has a first pinion gear, a second pinion gear, a first side gear, and a second side gear. The differential case has an accommodation part, a first sleeve that is connected to the accommodation part, a second sleeve that is connected to the accommodation part, an oil discharge groove that extends from an outer end part of the first sleeve to the inside of the accommodation part, and an oil introduction groove that extends from an outer end part of the second sleeve to the inside of the accommodation part. The oil introduction groove reaches an internal space of the accommodation part on a side further radially outward than the second side gear, and is disposed so as to overlap with neither the first pinion gear nor the second pinion gear.
