In an abnormal vibration detection device for an elevator car, which is installed in an elevator that moves up and down in a road and detects abnormal vibration of the car, a device that engages with a rotation shaft perpendicular to the vertical direction, A detection rod is attached to the car so as to be relatively rotatable, the detection rod is provided with a weight, the other end of the detection rod is suspended from the car by a spring, and the detection rod is attached to the car so that it can rotate freely. When vibration occurs in the car, the detection rod is configured to vibrate in the vertical movement direction relative to the rotating shaft in synchronization with the expansion and contraction of the spring, and the vibration of the detection rod in the vertical movement direction is exceeds a predetermined amplitude,
An abnormal vibration detection device for an elevator car, characterized in that a detection signal generating means for generating a detection signal is provided between the detection rod and the car.
