For the purpose, a physical quantity regarding a bearing body is detected by a detection sensor provided in the bearing body, and detection information of the detection sensor is transmitted by a wireless transmitting unit provided in the bearing body via wireless communication. At this time, the detection information is transmitted at a first transmission interval when the detection information is smaller than a threshold value and is a normal value, and the detection information is transmitted at a second transmission interval that is shorter than the first transmission interval when the detection information is the threshold value or larger and is an abnormal value.

A target substance capturing device includes a reflection surface on which a plurality of non-flat portions is arrayed, the reflection surface capturing a target substance, and reflecting irradiated light. The plurality of non-flat portions are arranged in an array, the array includes a plurality of unit arrays in which the plurality of non-flat portions are arranged such that each one center of the non-flat portions superposes a position of a vertex in an M-time symmetrical figure, and the plurality of unit arrays is arranged such that each one center of gravity of the M-time symmetrical figure superposes a position of an intersection of an N-time symmetrical lattice pattern, where M is an integer of two or more, and N is an integer of two or more and different from M.
