摘要： Provided is a canister that includes a first adsorbing layer K1 including a first adsorbing material Q1 as an adsorbing material Q and a second adsorbing layer K2 including, as the adsorbing material Q, a second adsorbing material Q2 different from the first adsorbing material Q1. The first absorbing layer K1 and the second absorbing layer K2 are provided inside a casing 10. In a flowing direction X of fuel vapor J between one end and another end of the casing 10, the first adsorbing layer K1 is disposed at a position in contact with an air port 10a at the other end, and the second adsorbing layer K2 is disposed closer to the one end than the first adsorbing layer K1 is. The first adsorbing material Q1 adsorbs the fuel vapor J at an adsorbing rate that is higher than an adsorbing rate of the second adsorbing material Q2.

摘要： Provided is a canister that includes a first adsorbing layer K1 including a first adsorbing material Q1 as an adsorbing material Q and a second adsorbing layer K2 including, as the adsorbing material Q, a second adsorbing material Q2 different from the first adsorbing material Q1. The first absorbing layer K1 and the second absorbing layer K2 are provided inside a casing 10. In a flowing direction of fuel vapor J between one end and another end of the casing 10, the first adsorbing layer K1 is disposed at a position in contact with an air port 10a at the other end, and the second adsorbing layer K2 is disposed closer to the one end than the first adsorbing layer K1 is. The first adsorbing material Q1 adsorbs the fuel vapor J at an adsorbing rate that is lower than an adsorbing rate of the second adsorbing material Q2.
