Support structure for wind power generation device and wind power generation device

A support structure for a wind power generation device comprising:

• a plurality of floats capable of floating on a water surface or in water;
• a connecting member connected to a first float among the plurality of floats and a second float among the plurality of floats;
• a support platform that is provided in a middle of the plurality of floats and supports a lower end of a tower part of the wind power generation device;
• a linear wire member having one end connected to the first float or the connecting member and the other end connected to the support platform;
• and
• a support member that is provided at the first float or the connecting member and supports the tower part supported on the support platform from a side such that the tower part is movable in an axial direction of the tower part,
• wherein in the first float and the connecting member, relative displacement that occurs between the first float and the connecting member is attenuated by a rigid body in viscous fluid filled between the first float and the connecting member.
