Abstract
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.
