る変速機油圧制御装置のマニアル弁。[Scope of Claim for Utility Model Registration] In a manual valve of a transmission hydraulic control device that controls the supply of hydraulic pressure to a forward friction engagement element and a reverse friction engagement element by switching the stop position of the spool, the spool is in the neutral position. The port of the manual valve and the land of the spool are arranged so that the line pressure oil passage communicates with the forward friction engagement element and the reverse friction engagement element through the orifice, respectively, when the line pressure oil passage is in the forward movement position than the orifice. The oil passage on the friction engagement element side and the oil passage on the reverse friction engagement element side from the orifice are each provided with a pressure retention valve at a position where the pressure is maintained only when the spool is in the neutral position. A manual valve for a transmission hydraulic control device, wherein the manual valve is set to a predetermined holding pressure value that is lower than a hydraulic pressure value that completely engages a forward friction engagement element and a reverse friction engagement element.
