Abstract: Provided is an evaporated fuel treatment device. The evaporated fuel treatment device includes a main body case and a lid. The lid includes a target port, and is configured to be attached to the main body case on an attachment surface defined in advance in the main body case. The target port is configured to guide a gas in a direction intersecting a flow direction of the gas in a target adsorption chamber. The lid is configured to be rotated along a rotation direction prior to being attached to the main body case, to thereby (i) allow selection of one attachment angle from two or more attachment angles and (ii) be attached to the main body case.

Abstract: A canister that adsorbs and desorbs an evaporated fuel generated in a fuel tank of a vehicle includes an outer case, an inner case, a connecting port, and a sealing member. The inner case has a cylindrical shape. The inner case is fitted into the outer case. The inner case is filled therein with an adsorbent in a granular form. The inner case includes a first end and a second end. The connecting port connects an inside and an outside of the outer case to each other. The sealing member is provided to the second end of the inner case located opposite to the first end leading to the connecting port. The sealing member seals a gap between the outer case and a joining portion of the inner case. The joining portion joins the inner case to the outer case.

Abstract: Provided is a canister that makes it possible to reduce production costs. One aspect of the present disclosure is a canister. The canister includes an outer case including a charge port that takes in an evaporated fuel, a purge port that discharges the evaporated fuel, and an atmosphere port open to the atmosphere, an inner case arranged inside the outer case, the inner case having an inner space to which the atmosphere port is connected, a first adsorption chamber arranged in the inner space of the inner case, and a second adsorption chamber arranged between the first adsorption chamber and the atmosphere port in a flow path of the evaporated fuel in the inner space of the inner case. A cross-sectional area perpendicular to a gas flow direction in the second adsorption chamber and a cross-sectional area perpendicular to a gas flow direction in the first adsorption chamber are different.

Abstract: A canister includes an activated carbon molding configured to adsorb an evaporated fuel originating in a fuel tank of a vehicle; and an adsorption chamber accommodating the activated carbon molding. A method of manufacturing the canister includes pressing fibrous activated carbons in a specific direction, or performing suction to thereby gather the fibrous activated carbons in the specific direction and mold the fibrous activated carbons into the activated carbon molding that has a columnar shape; and arranging, inside the adsorption chamber, the activated carbon molding produced such that a pressing direction or a suction direction for the activated carbon molding is perpendicular to a flow direction of the evaporated fuel.

Abstract: One aspect of the present disclosure provides a canister configured to adsorb and desorb fuel vapor generated in a fuel tank of a vehicle. The canister includes a charge port, a purge port, an atmosphere port, a first adsorption chamber and a second adsorption chamber directly coupled to the charge port and the purge port or indirectly coupled to the charge port and the purge port via an additional chamber, a first adsorption member housed in the first adsorption chamber, and a second adsorption member housed in the second adsorption chamber. The first adsorption member includes: an adsorption sheet formed of a fiber having properties to adsorb the fuel vapor; and granules having properties to adsorb the fuel vapor and arranged to be dispersed on a surface of or an inside of the adsorption sheet. The adsorption sheet is wound around or folded to form two or more layers.

Abstract: A canister that adsorbs and desorbs evaporative fuel generated in a fuel tank of a vehicle includes an adsorbent and a tubular body. A contact surface that is at least a partial area of an inner wall surface of the tubular body in a length direction of a central axis is brought into contact with a side surface of the inserted adsorbent to suppress movement of the adsorbent in a direction orthogonal to the central axis. The tubular body has an inclined surface in which the inner wall surface is inclined in a direction approaching the central axis of the tubular body in at least a partial area of an area from a starting point to the contact surface, the starting point being an opening end of an opening into which the adsorbent can be inserted.
