A blade assembly for a hydraulic power transmitting apparatus is made up of a plurality of blades disposed at an equal distance from one another; a joint piece provided at a radially outer end of each of the blades; and a tie member for tying the blades together at the joint pieces. The blades, the joint pieces and the tie member are integrally formed as a continuous semi-manufactured product of a belt-shaped metal plate. Each of the blades is raised or erected from a plane including the tie member. The joint piece is bent to change a direction of the tie member. The tie member containing therein a required number of blades is fixedly joined together at both ends into a ring shape.

Blade assembly for hydraulic power transmitting apparatus and method of manufacturing same

An impeller for a hydraulic power transmitting apparatus has a shell and a plurality of blades fixed to the shell. Each of the blades has a blade main body and a fixing flange which is bent at an angle relative to the blade main body. The shell and the fixing flange are placed one on top of the other and are pressed together at a fixing point such that a hollow cylindrical projection having a bottom is formed. The projection is made up of a diametrically expanded portion along a bottom outer periphery of that member out of the shell and the fixing flange which lies on an inner side in the projection. The expanded portion is thrusted into that member out of the shell and the fixing flange which lies on an outer side in the projection.
