3. The air cleaner for a vehicle of claim 2, wherein the cover member is a non-woven fabric having a plurality of vents so that air flows.

4. The air cleaner for a vehicle of claim 2, wherein the circumference of the cover member is fused to a step portion formed along a side wall of the inner periphery of the casing.

5. The air cleaner for a vehicle of claim 2, wherein the casing is fused to the housing by any one of ultrasonic fusion, thermal fusion, and vibration fusion.

6. An air cleaner for a vehicle, comprising:

a housing having an intake port for suctioning air and an outtake port for supplying the air suctioned through the intake port to an engine system of the vehicle; and

an element installed in the housing to filter the air suctioned through the intake port,

wherein the air cleaner includes an evaporation gas collecting unit installed at an upper part of the outside of the housing to collect evaporation gas which flows backward an engine and a noise attenuation member capable of reducing noise generated when air is suctioned is further included in the evaporation gas collecting unit.

7. The air cleaner for a vehicle of claim 6, wherein the evaporation gas collecting unit includes

a casing installed at the upper part of the outside of the housing and installed to be in communication with the inside of the housing and formed in a box shape having an accommodation space therein,

active carbon accommodated in the casing,
