Saddle-ridden type vehicle

A saddle-ride vehicle, comprising:

• a head pipe supporting a steering shaft connecting with a handlebar;
• a vehicle-body frame connecting with the head pipe;
• a fuel tank placed to a rear of the head pipe and supported on an upper portion of the vehicle body frame;
• a pair of canisters for absorbing evaporated fuel introduced from the fuel tank, the pair of the canisters being vertically placed under one side portion of the fuel tank in a position along the vehicle-longitudinal direction;
• coupling pipes connecting the pair of the canisters to each other in series arranged on the front of the pair of the canisters;
• and
• an evaporated fuel introducing pipe connecting one canister of the pair of the canisters to the fuel tank, a purge pipe connecting the one canister to an engine intake system, and an outside-air introducing pipe introducing outside air into the other canister arranged on a rear of the pair of the canisters.

• wherein the pair of the canisters include, respectively:
• evaporated fuel introducing ports for introducing evaporated fuel;
• drain ports for draining unwanted substances from the corresponding canisters;
• outside-air introducing ports for supplying outside air to absorbed fuel;
• and
• gas outlets for delivering, as a purge gas, the fuel absorbed in the canisters by outside air;
• the evaporated fuel introducing ports and the gas outlets are provided on one of an end of the respective canisters;
• the drain ports and the outside-air introducing ports are provided on the other end of the respective canisters;
• one canister of the pair of the canisters is arranged to have a first end oriented toward the rear of a vehicle body, and a second end oriented toward the front of the vehicle body;
• the other canister is arranged to have a first end oriented toward the front of the vehicle body, and a second end oriented toward the rear of the vehicle body;
• the absorption-system coupling pipe connected between the drain port of the one canister and the evaporated fuel introducing port of the other canister, and the purge-system coupling pipe connected between the outside-air introducing port of the one canister and the gas outlet of the other canister are arranged on the front of the pair of the canisters;
• and
• the evaporated fuel introducing pipe connecting the evaporated fuel introducing port of the one canister to the fuel tank, the purge pipe connecting the gas outlet of the one canister to the engine intake system, and the outside-air introducing pipe connecting the outside-air introducing port of the other canister to an outside-air introducing path of the vehicle body are arranged to the rear of the pair of the canisters.
