Abstract
A position shifting plate for an air blowing device includes a casing having an inlet defined in an underside of the casing and an outlet defined in an end of the casing. An annular neck extends from the underside of the casing and encloses the inlet. A gap is defined between the underside of the casing and the neck. A guide member extends from the underside of the casing. A shifting plate has a grated portion and a hole. A flange extends from the shifting plate and two rails extend inward from the flange so as to be movably inserted in the gap. The shifting plate movably contacts the guide member to shift the hole or the grated portion to cover the inlet of the casing.
