PURPOSE: To provide an impeller without deteriorating performance of a blower even in the case of mounting a load in a blow out side, while effectively applying a characteristic of the impeller of enlarging a diameter of one disk of two sheets of disks of mounting a blade member. CONSTITUTION: In an impeller A for a centrifugal blower formed by separating two sheets of disks 1, 2 of different diameter parallelly further concentrically and by mounting many blade members (a) in the periphery of these disks 1, 2 suitably with a fixed space, the blade member (a) is mounted in two sheets of the disks 1, 2 by providing a suitable angleθconformed to a blow out angle of the blower relating to a surface of the disks 1, 2.
