摘要： A hydraulic control device used in an automatic transmission includes an oil pump, a working pressure regulating portion, a first lubricant supply passage, a lockup switch mechanism, and a second lubricant supply passage. The oil pump is driven in accordance with rotation of a driving source. The working pressure regulating portion regulates a working pressure based on an oil pressure generated by the oil pump. The first lubricant supply passage supplies a back pressure of the working pressure to a lubricant passage. The lockup switch mechanism turns on/off a lockup clutch of the automatic transmission by switching a supply/discharge path of the working pressure to/from a fluid transmission apparatus of the automatic transmission. The second lubricant supply passage supplies the working pressure to the lubricant passage and is disconnected when a lockup clutch of the automatic transmission is turned on by the lockup switch mechanism.
