Claims

[Claims for Utility Model Registration] (1) A valve body disposed in the upper part of a planetary gear mechanism of an automatic transmission, a check ball being movably accommodated in an oil passage formed in the valve body, and a check ball being freely movable within the oil passage. The flow of oil in one direction is blocked by the check ball sitting on a seat formed in the oil passage due to the flow force of the oil, and the flow of oil in the other direction in the oil passage is blocked due to the flow force of the oil. A check ball structure for an automatic transmission in which a check ball is allowed to be spaced apart from the seat surface, characterized in that the check ball is arranged on the axis of an oil passage that directly connects the planetary gear mechanism and the valve body. Check ball structure for automatic transmission. (2) In claim (1), the valve body:
A check for an automatic transmission comprising an upper valve body, a lower valve body, and a plate, wherein the check ball is housed in the oil passage formed by the upper valve body and the plate. Ball structure.
