摘要：
A hydraulic control circuit includes an oil pump for generating a hydraulic pressure by being rotated by power of a driving force source, a line pressure oil passage in which at least a line pressure generated by adjusting the hydraulic pressure generated by the oil pump is supplied, a driving force source stopping unit that stops the rotation of the driving force source, and a hydraulic pressure reduction suppressing unit that is provided in the line pressure oil passage and suppresses a reduction of the line pressure accompanying reverse rotation of the driving force source when the rotation of the driving force source is stopped by the driving force source stopping unit.
