摘要：
The present invention provides an abnormality detector for a rolling bearing including an outer race, and an inner race. The abnormality detector includes a filter configured to prevent metal pieces contained in lubricating oil flowing through the bearing space between the outer and inner races from passing through the filter, while allowing the lubricating oil to pass through the filter so as to flow to the outside space of the bearing space; an electric circuit including a pair of permanent magnets mounted, as a pair of electrodes, to the filter so as to be spaced apart from each other, and lines extending from the respective electrodes to a power source; and an output detector configured to detect a change in electrical output from the electric circuit when metal pieces adhere between the pair of permanent magnets, thereby detecting the state of metal pieces contained in the lubricating oil.
