The resin member is arranged in an object chamber, which is any of the at least one chamber. An adsorbent arranged in the object chamber is formed as a plurality of granular bodies. The resin member is an integrally formed member of resin, and includes a coupling member and at least one rod-shaped unit. The at least one rod-shaped unit includes a plurality of rod-shaped portions extending from the coupling member in a direction substantially parallel to a direction intersecting a gas flow direction in the object chamber at an angle of 45° or more and 90° or less. ## Claims ### Claim 1 A canister configured to be mounted in a vehicle with an engine, the canister comprising: at least one chamber in which an adsorbent to adsorb fuel vapor is arranged; an inflow port configured to allow the fuel vapor to flow into the at least one chamber from a fuel tank of the vehicle; an atmosphere port configured to allow atmospheric air to flow into the at least one chamber from outside of the vehicle; an outflow port configured to allow the fuel vapor adsorbed on the adsorbent to flow out toward the engine by means of the atmospheric air flowing in from the atmosphere port; and a resin member arranged in an object chamber, the object chamber being any of the at least one chamber, the adsorbent arranged in the object chamber being formed as a plurality of granular bodies, the resin member being an integrally formed member of resin, the resin member comprising a coupling member and at least one rod-shaped unit, the at least one rod-shaped unit comprising a plurality of rod-shaped portions extending from the coupling member in an extending direction substantially parallel to a direction intersecting a gas flow direction in the object chamber at an angle in a range of from 45° to 90°; and at least a part of the plurality of rod-shaped portions having, on an outer peripheral surface thereof, at least one recess formed therein. ### Claim 2 (depends on 1) The canister according to claim 1, wherein the object chamber has an elongated shape extending in the gas flow direction in the object chamber. ### Claim 3 (depends on 1) The canister according to claim 1, wherein the resin member comprises, as the at least one rod-shaped unit, a first rod-shaped unit and a second rod-shaped unit, wherein the coupling member comprises a first portion and a second portion, the second portion being positioned on a side opposite to the first portion, wherein the plurality of rod-shaped portions in the first rod-shaped unit extends, from the first portion, substantially parallel to a direction determined according to the first rod-shaped unit, and wherein the plurality of rod-shaped portions in the second rod-shaped unit extends, from the second portion, substantially parallel to a direction determined according to the second rod-shaped unit. ### Claim 4 (depends on 3) The canister according to claim 3, wherein the first rod-shaped unit and the second rod-shaped unit have a substantially identical shape. ### Claim 5 (depends on 4) The canister according to claim 4, wherein the resin member has a substantially plane-symmetrical shape with respect to a plane passing through the coupling member. ### Claim 6 (depends on 1) The canister according to claim 1, wherein the extending direction of the plurality of rod-shaped portions is a direction intersecting the gas flow direction in the object chamber at an angle of approximately 90°. ### Claim 7 (depends on 1) The canister according to claim 1, wherein both ends of the resin member in the gas flow direction are positioned near an inner wall of the object chamber. ### Claim 8 (depends on 1) The canister according to claim 1, wherein the coupling member extends in the gas flow direction. ### Claim 9 A canister configured to be mounted in a vehicle with an engine, the canister comprising: at least one chamber in which an adsorbent to adsorb fuel vapor is arranged; an inflow port configured to allow the fuel vapor to flow into the at least one chamber from a fuel tank of the vehicle; an atmosphere port configured to allow atmospheric air to flow into the at least one chamber from outside of the vehicle; an outflow port configured to allow the fuel vapor adsorbed on the adsorbent to flow out toward the engine by means of the atmospheric air flowing in from the atmosphere port; and a resin member arranged in an object chamber, the object chamber being any of the at least one chamber, the adsorbent arranged in the object chamber being formed as a plurality of granular bodies, the resin member being an integrally formed member of resin, the resin member comprising a coupling member and at least one rod-shaped unit, the at least one rod-shaped unit comprising a plurality of rod-shaped portions extending from the coupling member in an extending direction substantially parallel to a direction intersecting a gas flow direction in the object chamber at an angle in a range of from 45° to 90°, the resin member comprising, as the at least one rod-shaped unit, a first rod-shaped unit and a second rod-shaped unit, the coupling member comprising a first portion and a second portion, the second portion being positioned on a side opposite to the first portion, the plurality of rod-shaped portions in the first rod-shaped unit extending, from the first portion, substantially parallel to a direction determined according to the first rod-shaped unit, and the plurality of rod-shaped portions in the second rod-shaped unit extending, from the second portion, substantially parallel to a direction determined according to the second rod-shaped unit. ### Claim 10 (depends on 9) The canister according to claim 9, wherein the object chamber has an elongated shape extending in the gas flow direction in the object chamber. ### Claim 11 (depends on 9) The canister according to claim 9, wherein the first rod-shaped unit and the second rod-shaped unit have a substantially identical shape. ### Claim 12 (depends on 11) The canister according to claim 11, wherein the resin member has a substantially plane-symmetrical shape with respect to a plane passing through the coupling member. ### Claim 13 (depends on 9) The canister according to claim 9, wherein the extending direction of the plurality of rod-shaped portions is a direction intersecting the gas flow direction in the object chamber at an angle of approximately 90°. ### Claim 14 (depends on 9) The canister according to claim 9, wherein both ends of the resin member in the gas flow direction are positioned near an inner wall of the object chamber. ### Claim 15 (depends on 9) The canister according to claim 9, wherein the coupling member extends in the gas flow direction.
