a spool that is slidably inserted into the spool and can assume a first position and a second position by sliding displacement, the spool having a hollow portion formed therein; A communication port is formed that connects to the hollow portion and opens to the outer peripheral surface of the spool, - the communication port communicates with the control pressure introduction port when the subur is in the first position, and the communication port communicates with the control pressure introduction port when the subur is in the first position; When in the position, it is cut off from the control pressure inlet,
The sliding displacement of the spool between the first position and the second position has hysteresis due to the action or non-action of control pressure on the inner end surface of the hollow portion through the communication port. A hydraulic control valve for an automatic transmission, characterized in that:
