A derailment detection apparatus for an elevator includes a conductive line, an upper support device configured to support an upper end portion of the conductive line, a lower support device configured to support a lower end portion of the conductive line, a contact element, which is installed on an ascending/descending body, and is brought into contact with the conductive line when the ascending/descending body derails from guide rail, and a detection unit configured to detect contact of the contact element with the conductive line. The lower support device is fixed to the guide rail by fastening a fastener, and is allowed to move upward and downward along the guide rail by loosening the fastener. The lower support device includes a guide portion configured to guide upward and downward movement of the lower support device along the guide rail.
