Claims

[Claims for Utility Model Registration] (1) A short cylindrical holding cylinder made by press forming a metal tube, having a first inward flange part at one end and a second inward flange part at the other end. , each having a holding housing formed therein and an outer diameter smaller than the inner diameter of the holding cylinder portion and larger than the inner diameter of both the first and second inward flange portions, and displaceably housed in the holding housing. A ball valve for an automatic transmission, wherein a mortar-shaped inclined surface with which the ball can come into close contact is formed on the inner peripheral edge of the inner surface of the first inward flange portion by surface pressing. (2) The corner that exists between the flat surface and the inclined surface that exists near the outer periphery of the first inward flange portion is
The ball valve for an automatic transmission according to claim 1, wherein the ball valve can freely come into contact with the outer surface of the ball. (3) A second inclined surface is formed around the inclined surface formed on the first inward flange portion, the second inclined surface forming a larger angle with the center line of the holding housing than the inclined surface. Ball valve for automatic transmission. (4) The ball valve for an automatic transmission according to claim 1, wherein the inclined surface has a convexly curved cross section. (5) A holding housing made by injection molding of synthetic resin and having an inward flange on one end of a short cylindrical holding cylinder and a plurality of locking protrusions on the inner peripheral surface of the other end; and a ball having an outer diameter smaller than the inner diameter of the cylindrical portion and larger than the inner diameter of the inward flange portion and the diameter of the inscribed circle of the plurality of locking protrusions, and displaceably housed in the holding housing. A ball valve for an automatic transmission, wherein a mortar-shaped inclined surface with which the ball can come into close contact is formed on the inner peripheral edge of the inner surface of the inward flange portion.
