In an impeller 1 in which a plurality of wear-resistant members 8 are attached to the inlet edges 6 of the blades, the inlet edges 6 of the blades slide along the direction of the blade inlet edges of the wear-resistant members 8. The wear-resistant member 8 is fitted with the guide rail 7 and has an engaging portion 9 that prevents it from escaping from the guide rail 7 in the right angle direction. An impeller characterized in that it is formed by pasting wear-resistant pieces, and a plurality of the wear-resistant members 8 are arranged and fixed in parallel along the guide rail 7 in close contact with each other. 2. Utility model registration claim 1, wherein the wear-resistant member 8 is provided with a stepped surface 15 substantially parallel to the bottom surface 14 of the wear-resistant piece on the surface of the wear-resistant piece that forms the interface 13 with an adjacent wear-resistant member. Impeller as described. 3. The wear-resistant member 8 has wear-resistant pieces attached partially double, and one of the end faces forming the boundary surface 13 with the adjacent wear-resistant member is the retaining plate 81 end face and the inner wear-resistant piece 82 ' end face. The impeller according to claim 1, wherein the end face of the outer wear piece 83' is retracted from the plane formed by the outer wear piece 83 ', and the other end face of the outer wear piece protrudes. 4 The edge of the inner wear-resistant piece 8 2 ′ on which the outer wear-resistant piece 8 3 ′ is formed by retracting the outer wear-resistant piece 8 2 ′ is notched 11 in a step-like manner. impeller.
