PROBLEM TO BE SOLVED: To provide a torque tube device can decrease a vibration in greater number of resonance modes, which is transmitted from a torque transmission shaft where a resonance of a bending vibration occurs to a torque tube through bearings. SOLUTION: The torque tube device 1 includes a torque tube 2 fixed and arranged between two power transmission devices 7 and 8, and a torque transmission axis 4 rotatably supported inside the torque tube 2 through bearings 3 and 3 for transmitting torque between the two power transmission devices 7 and 8. The two bearings 3 and 3 are provided inside the torque tube 2 so as to be spaced, and outer peripheries 3A thereof are provided slidably in a longitudinal direction of the torque tube 2 with respect to the torque tube 2. Inner peripheries 3B of the bearings 3 and 3 are provided slidably in a longitudinal direction of the torque transmission axis 4 with respect to the torque transmission axis 4.
