The second portion is attached to the first portion by engagement of the second engaging portion with the first engaging portion. The first portion includes a filtration member and a case. The case includes an inner chamber within which the filtration member is disposed. The case includes a drainage port configured to drain liquid that has infiltrated the inner chamber. The second portion is attached to the first portion to form a cover that covers the drainage port together with the first portion. The cover has an outlet that opens to the outside at a position lower than the drainage port.

Dust filter

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.

A dust filter includes a filter medium configured to filter foreign substances, such as dust, from atmospheric air. The dust filter also includes a case within which the filter medium is disposed. A first chamber in the case on one side of the filter medium defines a clean side, and a second chamber in the case on the other side of the filter medium defines a dirty side. The case includes a first port that provides fluid communication between the first chamber and the air passage, and a second port that provides fluid communication between the second chamber and the surrounding atmosphere. The second port is configured to allow water accumulated in the case to drain to the outside of the case by gravity while the case is mounted on the vehicle.

A canister includes a canister case. The canister case includes a tank port, a purge port, and an atmospheric port. An adsorbent () is disposed in the canister case. The canister case also includes a case body having a peripheral wall portion and an end wall portion, and a cover having an end wall portion closing the open end of the case body. The tank port and the purge port are formed to be arranged side-by-side on the end wall portion of the case body. The atmospheric port, a holding tube portion configured to receive an OBD module for communicating with the atmospheric port, and a mount piece configured to mount to a vehicle are formed on the end wall portion of the cover.
