<p>A hydraulic control device includes a first oil path; a second oil path; a third oil path; an engagement pressure generation unit; a signal pressure generation unit; and an internal pressure switching unit that switches between a non-reduced pressure state where locking occurs due to the signal pressure inputted and a source pressure is outputted unchanged as internal pressure to the first oil path, and a reduced pressure state where the signal pressure is not inputted and a hydraulic pressure is regulated to a constant pressure from the source pressure, based on a feedback pressure of the internal pressure and an urging force of a first urging unit, and outputted as the internal pressure to the first oil path.</p> |
