A tracked vehicle is provided with a sealing member between one side of the roller and the shaft for sealing oil for lubricating the bearing, and a lid having an oil supply hole for lubrication on the other side. In the upper roller device, the lid is formed with a bottom liner formed by roller forging and is integrated with the roller;
An oil supply hole is provided in the center, and a sleeve with the same diameter is provided between the outer races of the bearing, and this sleeve is press-fitted into the inner diameter of the roller, or the inner diameter of a bushing that has the same diameter as the inner diameter of this roller and is integrated with the roller. An upper wheel device for a tracked vehicle, characterized in that the thrust from the roller side is received at the other end of the shaft.
