Abstract
An abnormal vibration detecting device for detecting abnormal vibration of a rotational tub of a washing machine includes first and second abnormal vibration detectors. The first abnormal vibration detector includes a detecting lever rotatively moved where it collides with the rotational tub when it vibrates transversely, and a detection switch responsive to the rotative movement of the detecting lever. The second abnormal vibration detector includes a rotational speed detecting section detecting the rotational speed of a motor driving the rotational tub and a comparator section comparing a speed signal detected by the rotational speed detecting section with a reference speed signal determined based on the rise characteristic of rotation of the rotational tub appearing in the state that the rotational tub is in the condition of slight abnormal vibration.
