Abstract
An oil filler port of the capless oil feeder includes: an oil filler port main body made of a resin, a breather tube portion made of the resin, and a flap valve. The oil filler port main body has a tubular shape and includes a nozzle insertion port for inserting an oil filler nozzle at one end and a fuel feed port for supplying fuel to a filler tube at the other end. The breather tube portion is formed integrally on an outer side of a peripheral surface of the oil filler port main body and connected to a breather tube. The flap valve is foamed to be insertable from the fuel feed port, and is disposed inside the oil filler port main body to close the nozzle insertion port and is opened by insertion of the oil filler nozzle.
