Abstract
An air blower device has a tubular body defining an air guide passage and a ring-shaped member supported by the tubular body. The ring-shaped member has an extended part extending from the ring-shaped member toward the opening portion at the back of the tubular body. The extended part has an edge facing the opening portion at the back end of the tubular body, and the edge is located between an edge belonging to the ring-shaped member to face the opening portion at the back end of the tubular body and the opening portion at the back end of the tubular body. The ring-shaped member is supported by the tubular body by a contact between a first protrusion formed on an inner periphery of the tubular body so as to protrude from the inner periphery into the air guide passage and a second protrusion formed on the extended part.
