The semicircular canals and the vestibule are responsible for balance.
The fluid in the inner ears; the reason why you get dizzy when you spin around is because the fluid is sloshing around.
Balance
The ossicles are the three tiny bones in the middle ear that transmit sound vibrations. The sense of balance occurs in the fluid environment of the inner ear.
The 'vestibules' and semicircular canals of the inner ear are responsible for the sense of balance most animals have. Specifically, different fluids found in these stimulate motion sensors, which send the signals to the brain.
I'm presuming you are asking about equilibrium meaning about the sense of balance or position. The inner ear apparatus, or vestibulocochlear system, helps your body sense position and motion, with feedback from the proprioceptive nerve fibers throughout the body.
The inner ear.

The sense of balance, the organs are the 3 semicircular canals.
the inner ear
The ear is responsible for a human's sense of balance. Balance is basically determined by the amount of fluid found in one's inner ear.
The inner ear contains the sense organs for hearing and balance. The inner ear is comprised of two main functional parts: the vestibular system and the cochlea.

Motion sickness is caused by a conflict in what you sea with your eyes and your sense of balance (from the inner ears).
