The present disclosure disclosed a brake apparatus, a wheel body assembly and a rollator. The brake apparatus comprises a shaft body, a housing, a magnetic inductor and a magnet assembly, the housing is rotatable relative to the shaft body, the magnetic inductor is provided with a coil wound thereon, the magnet assembly includes a plurality of magnets spaced along the circumferential direction of the shaft body, wherein one of the magnetic inductor and the magnet assembly is connected to the shaft body and another one is connected to the housing so that when the housing rotates relative to the shaft body, the coil is capable of cutting magnetic field formed by the magnet assembly, thereby generating resisting force opposite to a rotation direction of the housing or the shaft body, which can play a braking role on the wheel body integrated or connected with the brake apparatus. And because the braking force is related to the rotation of the housing or the shaft body, rather than friction braking, it will not produce an emergency stop effect, which is safer and also can reduce wear and improve the service life of the brake device. Meanwhile the brake device is simple in structure and easy to prepare.
