材。[Claims for Utility Model Registration] A wear-resistant member for a blower formed of a plurality of wear-resistant pieces attached to the inlet edge of a blade of a blower impeller, each of the wear-resistant pieces being made of ceramic and having a U-shaped cross section. The blades are arranged adjacent to each other so that the inlet edges of the blades are fitted into the U-shaped grooves, and wear-resistant pieces are stacked in two layers on the portions of the inlet edges near the main plate, and 1. A wear-resistant member for a blower, characterized in that the boundary line between the wear-resistant pieces of the layer and the boundary line between the wear-resistant pieces of the outer layer are staggered so that they do not overlap.
