Abstract
A fuel supply device includes a valve body and a filter unit accommodating an air filter and a valve cap are attached to a tubular portion provided on a side surface of an inlet pipe. When a fuel tank has a negative pressure, the valve body opens and the negative pressure is eliminated by clean atmospheric air introduction. A projection portion is provided on the filter unit side of the valve body. Accordingly, attachment of the valve body into the tubular portion and attachment of the tubular portion and the filter unit are reliably performed, the reliability of valve body opening and closing is improved, and attachment workability is improved.
