A dustproof member includes a lower face and an upper face. The lower face is spaced from the open end of the shaft tube. The dustproof member covers the opening. The upper face of the dustproof member abuts a bottom of the shaft seat. The dustproof member has an outer diameter larger than an inner diameter of the shaft tube. The dustproof bearing assembly can be used in a motor.
