Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a jet fan, which is installed by being suspended from a ceiling of a tunnel, capable of performing vibration measurement without closing a lane.SOLUTION: A jet fan 1 comprises: a cylindrical casing 2; a motor 3 installed in the cylindrical casing 2; an impeller 4 mounted on a rotational shaft of the motor 3; a reinforcing plate 14 to hold the cylindrical casing 2; and a side section supporting member 13 fixed to the reinforcing plate 14. The jet fan 1 is installed on a ceiling wall 25 of a tunnel through the side section supporting member 13. A vibration sensor 15 which detects vibration during operation is fixed to the reinforcing plate 14. Ventilation of the tunnel is performed with the vibration sensor 15 fixed to the reinforcing plate 14.
