A proximity sensor (22), which generates an alternating current magnetic field in the direction of a guide rail (B) and detects a detection object by a loss of energy caused by a current which this alternating current magnetic field generates to flow to the detection object, is provided at the front end of each transport mover (V); a rear-end collision prevention detection plate (23), which enters between the guide rail (B) and the proximity sensor (22), is provided at the rear end of each transport mover (V); and a stopping device (W), which faces toward the proximity sensor (22) and forms a resonant circuit resonating at the generation frequency of the proximity sensor (22), is provided at a mover stopping location on the guide rail (B).
