Abstract:
Provided is a transmission device that can suppress a decline in a supply amount of oil to a catch tank. One aspect of the present disclosure pertains to a transmission device provided with a transmission mechanism and a gear case which accommodates the transmission mechanism. The transmission mechanism has an input gear, a counter gear, and a ring gear. The gear case has: a catch tank; a guide which sends oil scraped up by the ring gear to the catch tank; and a guiding part which is arranged so as to be shifted from the guide in the axial direction of the ring gear and which guides oil to the guide. The guide has an upstream end and a downstream end in an oil flow direction. The upstream end is located on the outer side in the radial direction of the ring gear. The induction part extends from a first end connected to the upstream end of the guide to a second end which overlaps with the ring gear when viewed from the axial direction of the ring gear.
