Claims

[Claims for Utility Model Registration] (1) A short cylindrical holding cylinder made by press forming a metal plate, with an inward flange at one end and a bent part protruding inward at the other end. a holding housing formed with an outwardly directed flange portion that protrudes outward, and an inner diameter smaller than the inner diameter of the holding cylinder portion;
and a ball having an outer diameter larger than the inner diameter of the inward flange part and the maximum diameter of the opening on the side where the bent part is formed, and is displaceably housed in the holding housing, and the inner peripheral edge of the inner surface of the inward flange part. A ball valve for an automatic transmission, wherein the ball valve has a mortar-shaped inclined surface in which the ball can come into close contact with the ball valve. (2) The ball valve for an automatic transmission according to claim 1, wherein the bent portion projecting inward and the outward flange portion projecting outward are formed continuously in the circumferential direction. (3) According to claim 1, wherein the inwardly projecting bent portions and the outwardly directed outward flange portions are formed in a tongue shape and are provided alternately in the circumferential direction. Ball valve for automatic transmission.
