Abstract

PURPOSE:To simplify the manufacture of a stopper by providing an annular chamber which is connected to the lubricating passage of a driving shaft, on a stopper in such a way that it opens onto a contact face with an inner ring, and providing a cut-off part which is connected to the annular chamber while also opening onto said contact face, on said stopper. CONSTITUTION:A stopper 8 for preventing the upward movement of the inner ring 7a of a bearing 7 is fixed to a driving shaft 6. An annular chamber 8c which is connected to the lubricating passage 6a of the driving shaft 6 is provided on the stopper 8 in such a way that it opens onto a contact face 8d with the inner ring 7a. And, a cut-off part 8e which is connected to the annular chamber 8c while opening onto the contact face 8d is also formed on the stopper 8 as a lubricating passage to the bearing 7. Thereby, the cut-off part 8e can be formed at the same time when the stopper 8 is formed.
