Abstract:
A state detection device according to the invention includes a strain gauge that detects a physical state of a tapered roller, and a processing portion that obtains a detection signal that is output from the strain gauge, performs processing on the detection signal, and transmits detection data obtained by performing the processing on the detection signal, to an outside. The strain gauge and the processing portion are accommodated in a through-hole formed at an axis center of the tapered roller.
