Abstract:
Provided is a transmission device that enables suppression of a decrease in bearing lubricity regardless of the rotational speed of a ring gear. One embodiment of the present disclosure is a transmission device comprising: a transmission mechanism; and a gear case in which the transmission mechanism is housed. The transmission mechanism comprises an input gear, a counter gear, and a ring gear. The gear case comprises: a catch tank; a guide that is positioned at a higher location than that of a counter gear bearing and that feeds oil scooped up by the ring gear to the catch tank; a first counter gear flow path for sending oil from the catch tank to the counter gear bearing; and a second counter gear flow path for sending oil scooped up by the ring gear directly to the counter gear bearing. The second counter gear flow path is positioned at a lower location than an upstream end of the guide.
