Abstract
A rotary resistance device providing resistance to rotary object includes a magnetic field generating assembly having a magnetizable main body, an even number of magnetizable extended bodies, magnetizable coils and separators, two first caps, and two shaft sections; a magnetizable outer cylinder enclosing the magnetic field generating assembly therein and rotatably connected to the shaft sections; and a magnetorheological fluid filled in a space formed between the magnetic field generating assembly and the magnetizable outer cylinder. The magnetizable extended bodies have the magnetizable coils wound thereon and are radially equally spaced on the magnetizable main body; the separators are respectively connected to between two adjacent magnetizable extended bodies; the first caps are closed onto two ends of the assembled magnetizable main body, magnetizable extended bodies and separators to seal the magnetizable coils in the magnetic field generating assembly; and the shaft sections are fixedly connected to the first caps.
