1. 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 a second protrusion portion that protrudes in a radial direction is provided on an outer peripheral surface of the first float,
the connecting member includes a second annular member in which a second opening portion for inserting the first float is formed inside, and
the connecting member is installed on the first float such that a lower end of the second annular member comes into contact with the second protrusion portion.
