1. A balancing apparatus comprising:
an elevator winding drum connected to an elevator car;
a center gear part connected to a first driving shaft of the elevator winding drum and including a first center gear; and
an outer gear part including a first outer gear which contacts and rotates with the first center gear;
a moving part which is relatively movable with respect to the center gear part in a state in which the moving part is connected to the outer gear part; and
a balancing weight which is disposed at one side of the moving part; and
a load control part capable of applying a force to the moving part, wherein, when the elevator winding drum receives a force in a first direction by the elevator car, the center gear part applies a force with respect to the elevator winding drum in an opposite direction of the first direction by a force applied from the outer gear part,
when the moving part is moved down by the load control part, the outer gear part rotate the center gear part,
wherein the center gear part includes:
a first center gear and a second center gear which rotate in contact with each other, and
the first center gear is connected to the first driving shaft,
wherein the outer gear part includes:
a first outer gear engaged with the first center gear; and
a second outer gear engaged with the second center gear,
wherein the first center gear and the second center gear are fixed in the gravity direction, and the first outer gear and the second outer gear are provided so as to be movable in the gravity direction.
