Abstract:
1. A power transmission apparatus comprising: three shafts being rotatably supported in a case and being interlocked with one another through gears; one of the shafts being positioned higher than the other shafts; opposite ends of the higher shaft each facing the outside of the case through an opening of the case; respective seals configured to seal gaps between the higher shaft and openings of the case, respectively; a lubricant guide configured to receive lubricant splashed up by the gears of the lower shafts and guide the received lubricant toward the one of the respective seals and not toward another of the respective seals; one of the lower shafts having the gears that are arranged in parallel and apart from each other in an axial direction of said one of the lower shafts, one of the gears of said one of the lower shafts meshing with the gear of the higher shaft and the other of the gears of said one of the lower shafts meshing with the gear of another one of the lower shafts; the lubricant guide having a channel longitudinally extending along said one of the lower shafts so that the lubricant guide receives lubricant splashed by at least any one of the gears of said one of the lower shafts and guides the received lubricant toward said one of the seals; said one of the seals lubricated by the guided lubricant; the other of the seals lubricated by lubricant splashed by at least any one of the gears of said one of the lower shafts; the case including a first case part and a case cover, the first case part being supported on a stationary side to define a chamber, the higher shaft being accommodated within the chamber, and the case cover being fixed to an end of the first case part so that the first case part and the case cover rotatably support the higher shaft that is accommodated within the chamber, the case cover having the opening through which the end of the higher shaft faces the outside of the case; the chamber having a form accommodating the higher shaft, the gear of the higher shaft, said one of the lower shafts, and the gears arranged in parallel on said one of the lower shafts; and the channel being integrally connected to the first case part and longitudinally extending within the chamber toward the case cover.
