本發明係關於一種轉動向阻力器，用於提供旋轉物體阻力，其包括磁場生成部，具有導磁本體、偶數導磁延伸體、偶數導磁線圈組、偶數阻隔體、二第一蓋體及二軸體，該等導磁延伸體等角度環設於導磁本體，各該導磁線圈組套設於各該導磁延伸體，各該阻隔體連接於相鄰之二導磁延伸體之間，該等第一蓋體設於該導磁本體、該等導磁延伸體及該等阻隔體之兩側以形成一封閉空間來容置該等導磁線圈組，該等軸體分別設於該等第一蓋體；導磁外滾筒，包覆磁場生成部，並且樞接於該等軸體；及磁流變液，填充於磁場生成部與導磁外滾筒之間。
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.
