[

When the air cleaner 1 is used for a long period of time, a large amount of impurities are adsorbed on the element 30, and the filtration function can not be properly performed. Therefore, after a predetermined time has elapsed, the element 30 installed in the body part 10 and the cover part 20 should be replaced with a new element to filter the air.

However, since the conventional air cleaner 1 is combined with the bolts of the body 10 and the cover 20, the bolts fixing the four corners of the body 10 and the cover 20 And then the element 30 needs to be replaced, so that the replacement operation is inconvenient and the replacement takes a long time.

In the conventional air cleaner 1, since the element 30 is positioned on the upper side of the body 10, the lower side of the element 30, that is, the lower side of the body 10, When the air is introduced through the air intake port 12, the element 30 is shaken by the flow pressure of the air and collides with the body 10 and the cover 20 to generate a vibration sound.

In order to solve the above-mentioned conventional problems, the present applicant has filed Korean Patent Application No. 10-2013-0061599, entitled Air cleaner for vehicles. However, in the case of the above-described technique, the element 30 can be easily attached to and detached from the air cleaner by a drawer, so that the element can be easily and easily replaced. However, .

In addition, in the conventional air cleaner 1 described above, in addition to the air cleaner 1, components for other vehicles are installed in various forms around the air cleaner 1 in a state of being mounted in the engine room of the vehicle. 2, there is a disadvantage in that insertion of the element 30 into the air cleaner 1 is inconvenient due to interference of other components installed around the air cleaner 1.
