Abstract
A dust filter is configured to filter air drawn into a vehicle canister. The dust filter includes a filtration member and a case. The case has an inner chamber for accommodating the filtration member. The case has a drainage port for draining liquid that has infiltrated the inner chamber. The drainage port is at least one opening formed at the bottom of the inner chamber. The case includes a cover that covers the drainage port. The cover has an outlet that opens to the outside. The outlet is lower than the drainage port. At least one baffle plate is disposed inside the cover. The baffle plate has a slope on the side of the baffle plate facing the drainage port, thereby forming a ramp.
