SENSOR UNIT

A signal output part of a first sensor configured to output a signal corresponding to an operation state of a mechanism for locking rotation of a steering shaft is mounted on a first circuit board. A signal output part of a second sensor configured to output a signal corresponding to an operation state of a mechanism for detecting a rotation angle of the steering shaft is mounted on a second circuit board. A connector electrically connects the first circuit board and the second circuit board while allowing relative displacement therebetween.
