力伝達装置における潤滑機構。 A pinion shaft that meshes with the rear output gear of a power transmission mechanism for a four-wheel drive vehicle is inserted into an extension housing that is assembled to the rear part of a case that houses the mechanism and extends rearward, and the pinion shaft is inserted into an extension housing that extends rearward. A sleeve yoke is rotatably supported inside the housing via a tapered roller bearing, and is assembled to the outer periphery of the rear end of the pinion shaft so as to transmit torque, and to which the front end of the propeller shaft is connected. Lubricating fluid-tightly and rotatably supported through a bushing and a sealing member assembled to the rear end opening of the housing, and introduced into a space between the tapered roller bearing and the bushing within the housing. In the power transmission device for a four-wheel drive vehicle in which the bushing and the sealing member are lubricated by oil, there is provided a power transmission device for a four-wheel drive vehicle, which extends in the front-rear direction at the bottom of the bushing assembly portion of the housing and is connected to the space and the front end of the sealing member. Lubrication in a power transmission device for a four-wheel drive vehicle, characterized in that an oil passage that opens is provided, and a pair of ribs protruding inwardly on both sides of the inner periphery of the housing forming the space are provided in the front-rear direction. mechanism.
