Claims

[Scope of utility model registration request]

In an endless track roller, a roller is rotatably supported on a roller shaft supported by left and right bearings, and an annular oil chamber is provided inside the roller so as to surround the shaft. An oil supply conduit is provided that communicates with the floating seal mounting part from the side opening in the axial direction at the upper position, and an oil drainage conduit opposite to the oil supply conduit is provided in the axial direction at the lower position of the other bearing. A roller lubrication structure for an endless track, characterized in that a floating seal mounting portion is provided to communicate with a side opening, and the oil chamber is formed in a substantially V-shape with a gentle slope in cross section.
