A vehicle pipe member comprising:
- a first end connected to a canister that adsorbs fuel boil-off gas in a fuel tank;
- a second end open to an atmosphere;
- a pipe body comprising an intermediate portion in a length direction and a bent portion formed at the intermediate portion;
- a plurality of adsorbing members that fill the pipe body to adsorb the fuel boil-off gas in gas discharged from the canister to the atmosphere;
- and
- at least one support member that is provided within the pipe body to support an inner diameter of the pipe body,
- wherein the at least one support member is disposed at the bent portion.
A method for manufacturing a vehicle pipe member,
- wherein the vehicle pipe member comprises a first end connected to a canister that adsorbs fuel boil-off gas in a fuel tank and a second end open to an atmosphere;
- wherein the method comprises:
- a first step for disposing a plurality of adsorbing members and at least one support member within a pipe body having a straight pipe shape, the plurality of adsorbing members adsorbing the fuel boil-off gas in gas discharged from the canister to the atmosphere, and the at least one support member supporting an inner diameter of the pipe body;
- and
- a second step for forming a bent portion of the pipe body by bending the pipe body at a location where the at least one support member is disposed.
