PROBLEM TO BE SOLVED: To provide an LED lighting device for the in-warehouse work of a car carrier capable of easily changing an irradiation direction with excellent heat dissipation efficiency in spite of a sealing type, and capable of changing the irradiation direction with a life of an LED element elongated. SOLUTION: The LED lighting device is composed of a lighting device body equipped with a reflecting plate fixed with a straight-tube LED lamp in which a cross-section flat or mound shape substrate with a plurality of LED light-emitting diode elements (LED elements) arranged in one or a plurality of lines underside is inserted into and arranged in a transparent or translucent cylindrical straight tube, and a globe for covering the body. Both ends of the straight-tube LED lamp are fitted into coat covers for sealing ends and cylindrical vibration-isolating rubber, respectively, and furthermore, the LED lighting device includes a U-shaped fixing cap for capturing the vibration-isolating rubber, and inserted and fixed into an insertion-coupling hole of a fixing member with both legs arranged at ends of the lighting device.
