Abstract:
Provided is a transmission device that can curb deterioration of lubricity of a bearing. One aspect of the present disclosure is a transmission device comprising a transmission mechanism, and a gear case that houses the transmission mechanism. The transmission mechanism includes an input gear, a counter gear, a ring gear, a first differential case bearing, and a second differential case bearing. The gear case includes a catch tank, a guide that sends oil moved up by the ring gear to the catch tank, and a buffer part that sends, to the second differential case bearing, some of the oil flowing through the guide. The ring gear is a twisted helical gear configured to send the oil to the first differential case bearing side along an axial direction of the ring gear when the ring gear rotates in a direction in which the oil is moved up toward the guide.
