description	PROBLEM TO BE SOLVED: To solve a problem that since a jet fan for ventilation in an automobile road tunnel is installed in a state of being hung from the tunnel ceiling, component parts of the jet fan and the jet fan itself have the potential of falling, but there is currently no system for simply achieving a mechanism capable of beforehand predicting falling of the jet fan.SOLUTION: A jet fan includes a blast tube equipped with a motor and impellers fitted on a rotating shaft of the motor inside a cylindrical casing and a silencing tube of the cylindrical casing on both sides of the blast tube. A position detecting sensor is provided in an end of an upper portion of the silencing tube and a controller is provided for detecting displacement of a distance between a tunnel ceiling surface and a jet fan end.
