Title:
IMPELLER OF FLUID TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JPS58659
Kind Code:
A
Abstract:
PURPOSE:To eliminate looseness of a blade without causing the increase of weight and the worsening of workability, by previously forming a claw of the blade to curved shape arranged with a distance between the outermost parts in the direction of its width at least slot width of a shell and resiliently contacting the both claw of the blade and slot of the shell. CONSTITUTION:A slot 1b formed in an impeller shell 1 is formed in similar width to a conventional one, and a claw 2b' of a blade, in plate thickness smaller than width of the slot 1b, is driven into said slot 1b. Then the claw 2b' is formed with a step difference almost in the central part, and curved to shape with a distance between the outermost sides at least the width of the slot 1b. Accordingly, the claw 2b' can be resiliently contacted to side walls of the slot 1b in its both sides and surely fixed.
