ABSTRACT:
An evaporative fuel apparatus includes a first purge passage which connects a canister and an intake passage of an internal combustion engine and through which fuel vapor, stored in the canister, is purged into the intake passage, a control part provided in the first purge passage for controlling a flow of fuel vapor being fed from the canister to the intake passage, a detecting part for detecting a malfunction occurring in the control valve, a second purge passage which connects the canister and the intake passage and through which fuel vapor, stored in the canister, is purged into the intake passage, and a passage switching part for carrying out a passage switching to the second purge passage if a malfunction is detected by the detecting part, allowing the fuel vapor from the canister to be fed into the intake passage through the second purge passage.
