A washing machine has an abnormal vibration sensing apparatus. The abnormal vibration sensing apparatus includes a limiter having at least one opened side and connected to one of a vibrating body and a fixing body, a sensing rod having one end that is received in the limiter and separated from an inner wall of the limiter, and the other end that is connected to another of the vibrating body and the fixing body, and a contact sensing unit sensing whether the limiter and the sensing rod are in contact with each other so as to sense abnormal vibration of the vibrating body. According to this construction, it is possible to easily detect abnormal vibration in a plurality of directions without increasing the number of installing abnormal vibration sensing apparatuses.
