<p>The present invention relates to an air filter fixating device having an air filter shaped into multiple rolls for an air filter system for a vehicular air duct, wherein an air filter shaped into multiple rolls for separately filtering foreign substances of various sizes filters foreign substances according to size through each roll filter in order to significantly improve filtration efficiency and reduce the use of air filters. To achieve this, the air filter system with an air filter shaped into multiple rolls for a vehicular air duct includes: two or more roll type air filters linked with the rotation of a winding reel and buried in a housing to be transferred; a power transmission shaft buried in the housing to be moved in an axial direction and to be rotated; a movable power transmission shaft linear operating plate as a flat plate, wherein a bolt hole is formed at the center; and a second driving unit coaxial with a rotary shaft to be fixated to the inside of the housing, wherein a bolt shaft is joined to the bolt hole of the power transmission shaft linear operating plate to be rotated.</p> |
