To improve adsorption efficiency of active carbon of canister for a fuel tank cap with active carbon that adsorbs fuel in a tank.SOLUTION: A canister 10 for a fuel tank cap used for the fuel tank cap includes an attachment part which is attached to the fuel tank cap, and includes a base part with a communication hole formed which communicates with the interior of a fuel tank on either one of approximate center part or outer edge part neighborhood and a case member which is assembled onto the base part and in which a volume part is formed. A spiral rib extended from either one of a surface opposite to the base part of the case member or a surface opposite to the case member of the base part toward either one of the base part or the case member is formed on the volume part. The spiral rib constitutes an adsorption passage whose one end connects with the communication hole and the other end connects with an atmosphere communication hole 22 formed on either one of outer peripheral neighborhood or approximate center part of the surface opposite to the base part of the case member, and the adsorption passage is filled with an adsorption means.SELECTED DRAWING: Figure 1
