Abstract: PURPOSE: A drain structure of a hydraulic valve is provided not to reduce responsibility of an automatic transmission without hindrance for a movement of a spool of viscous oil by exhausting oil. CONSTITUTION: A drain structure of a hydraulic valve comprises a sleeve(2) and an exhaust chamber(3). The sleeve covers an exhaust end(1b) formed to drain leaking oil through land portions(1a,1a'). Land portions open and close a passage formed integrally to a spool embedded in a valve body by a movement. The exhaust chamber is formed to a plug(2'). The exhaust chamber comprises a filled space(3a) and an exhaust port(3b). The filled space is filled with oil flown in through a gap of the spool. The exhaust port is formed to an upper portion of the filled space to form a regular gap not to shut completely the filled space with a diameter of the exhaust end. The filled space forms step walls(3a') to correspond to an end of the exhaust port in step. Therefore, reduction of moving speed of oil in the exhaust chamber is prevented when the spool is returned by preventing increase of oil pressure filled in the exhaust chamber with the gap.
