A changeable damping wave power capturing device driven by bidirectional screw rod is provided, which uses the ball screw device to capture the wave power and prevents the energy lost caused by complex mechanism. In addition, bidirectional reciprocating rectilinear motion is changed to unidirectional rotation by the ratchet wheel device, and then the rotating energy is imported to the generating set. Besides, the wave power capturing device driven by bidirectional screw rod uses the control device to detect wave energy and choose different generator, the control device could change the damping value and improve the efficiency that transforming wave energy.
