Abstract

PURPOSE:To enhance the precision of the vane wheel by forming a plurality of vane insertion grooves provided on the outer periphery of a hub with the depth as smaller as possible. CONSTITUTION:A plurality of vane insertion grooves 3 are formed in the outer- peripheral surface 2 of the hub 1. Each of the vane insertion grooves 3 is inclined from the axial line of the hub 1 and the depth thereof is made as smaller as possible. Each vane insertion groove 3 is used mainly for positioning the vane 4 at the time when the welding thereof is started, while the retention of the position and strength of the vane 4 is achieved by the joint part of the hub 1 and the vane 4 positioned on the outer-peripheral surface of the hub 1. And, the vanes 4 are fixed to the hub 1 by welding by using electron beams and the like along the whole periphery of the lateral surface as deep as the insertion grooves 3 in the lateral surface of the hub 1 and along the insertion sueface of the outer-peripheral surface of the hub 1.
