Roll mount

A roll mount comprising:

• a rubber coupled to a core is mounted in an exterior pipe coupled to an end of a main body, slits are formed in the rubber at a periphery of the core, and a pocket is disposed within the slits, wherein the pocket includes:
• a first pocket portion having a first chamber formed therein;
• a second pocket portion having a second chamber formed therein;
• and
• connecting portions that have flow paths that connect the first pocket portion and the second pocket portion and the first chamber and the second chamber are in fluid communication with each other,
• wherein a magnetorheological fluid is encapsulated in the first chamber and the second chamber, the magnetorheological fluid flows through the first chamber and the second chamber via the flow paths based on elastic deformation of the first pocket portion and the second pocket portion, a coil is wound at exterior sides of the first pocket portion and the second pocket portion, and fluidity of the magnetorheological fluid is adjusted based on the amount of electric current applied to the coil,
• wherein the slits are formed at a first side and a second side around the core, one on each side, respectively, the first pocket portion and the second pocket portion are detachably coupled to the slits, respectively, and an opening portion is formed to dispose the core between the first pocket portion and the second pocket portion, and
• wherein the coil is disposed on upper surfaces of the first pocket portion and the second pocket portion, and wound in a spiral orientation that extends radially from a center of the opening portion between the first pocket portion and the second pocked portion.
