Claims

[Claims for Utility Model Registration] 1. A bearing in which a plurality of outer rings are rotatable via rolling elements with respect to a plurality of inner rings that are respectively fitted and held on a common fixed shaft, the bearing In a device for supplying and draining lubricating oil to a group of bearings arranged in parallel with a saddle in between, at least one of a lubricating oil supply passage and an oil drainage passage is connected to a passage formed in the saddle and a lubricant oil drain passage. A lubricating device characterized in that it is constituted by an oil supply pipe or an oil drain pipe connected to a passage. 2. A request for registration of a utility model in which either the oil supply passage or the oil drainage passage comprises an oil supply passage or oil drainage passage formed in the fixed shaft and an oil supply hole or oil drainage hole formed in the inner ring so as to communicate with the oil supply passage or oil drainage passage. The lubricating device according to item 1.
