  • the length adjustment member 172 is coupled to the length adjustment bar 171 in a screwing method to adjust the length of the length adjustment bar 171 protruding from one side surface of the protrusion 151 and inserted thereinto according to the rotation.
  • the angle adjustment member 173 is coupled to the end of the length adjustment bar 171 .
  • the outer surface of the angle adjustment member 173 and the locking protrusion 152 of the clearance groove 153 of the resistance plate 140 face each other and are parallel with each other.
  • a distance between the first outer surface or the second outer surface of the protrusion 151 and the angle adjustment member 173 increases or is reduced, such that the range of the rotation angle of the resistance plate 140 rotated about the rotary support bar 130 is adjusted.
  • the resistance plate structure of the energy generation apparatus of the present invention can control the resistance force generated when the resistance plate 140 is in the vertical state, and accordingly, can control the rotation speed of the rotary body 120 , and also, can prevent an overload of the power generator, such that the maintenance and management can be easily performed and the cost for maintenance and management can be reduced.
