PROBLEM TO BE SOLVED: To eliminate excess processes of knurling work and the like, and exert no wrong effect in a size of an axial flow fan by arranging a bearing side shaft part which consists of a hollow cylindrical metallic shaft part, and a resin shaft part which is formed integratedly at an axial direction inner side of the metallic shaft part and which is tightly fitted to inner and outer peripheral surfaces. SOLUTION: A shaft for a cross flow fan is composed of a hollow cylindrical metallic shaft part 1 and a resin shaft part 2 formed integratedly with an outer peripheral part and a hollow part of an inside at an axial direction inner side of the metallic shaft part 1. A pair of penetrating holes 1a which are opposed to each other are disposed in an inside of the axial direction of the metallic shaft part 1. The resin shaft part 2 is composed of an inner shaft part 2a which is filled and hardened into the hollow part of the metallic shaft part 1, an outside shaft part 2b disposed on an outer peripheral surface of the metallic shaft part 1, and a cylindrical inner shaft part 2c disposed on an inside of the axial direction, a flange part 2d disposed on an outside of the axial direction of the outside shaft part 2b, and a connecting part 2e which is filled and hardened into each penetrating hole 1a, and they are integratedly formed. |
