Disclosed is a device for detecting the omission of a fastener. According to an aspect of the present invention, the device for detecting the omission of a fastener comprises a sensor part including a proximity sensor for detecting a conductor approaching a detection surface; a buffering part arranged at the upper side of the sensor part and including a spring for absorbing a shock; and a detection part arranged at the lower part of the sensor part. The detection part includes a detection bar housing having slots formed on both upper side surfaces and having a penetrating hole formed on a bottom surface; and a detection bar composed of a conductive material that is exposed to the bottom surface of the detection bar housing through the penetrating hole of the detection bar housing, and moving upward in the detection bar housing by the height of the fastener if a lower end thereof is in contact with the fastener. |
