PROBLEM TO BE SOLVED: To provide a drive device having a parallel link mechanism formed such that an operating range, especially, the deformation range of a roll shaft is enlarged. SOLUTION: The drive device having the parallel link mechanism P is constituted such that the device is provided with a roll shaft rotation angle amplifier 10 to amplify an angle of rotation around a roll shaft, a base member 20 disposed separately by a given distance from the roll shaft rotation angle amplifier 10, the given number of drive links 30, a fixed link 40, and a deformation part link 50. The roll shaft rotation angle amplifier 10 has a reference axis 11, a low speed axis 12, and a high speed axis 13. The drive link 30 and the fixed link 40 have the respective predetermined numbers of degrees of freedom. The drive link 30 has one end joined in a proper position with the reference axis 11, and the other end joined in a proper position with the base member 20. The fixed link 40 has one end joined in a proper position with the low speed axis 12, and the other end joined in a proper position with the base member 20. The deformation link 50 has a base end joined in a proper position with the high speed axis 13. COPYRIGHT: (C)2005,JPO&NCIPI
