<p>In order to improve the mountability in an engine, an oil pressure control apparatus includes: a pump that ejects oil by being driven by rotation of an engine; a first flow passage that interconnects the pump and a first predetermined portion; a second flow passage that is branched from the first flow passage and that supplies oil to a second predetermined portion; and a flow passage area adjusting portion that adjusts a flow passage area of the second flow passage according to a pressure of oil in the second flow passage; wherein the flow passage area adjusting portion is configured including a spool that is formed such that a first pressure receiving face and a second pressure receiving face having an area smaller than that of the first pressure receiving face oppose each other with the second flow passage interposed therebetween, and that can move according to a pressure of oil in the second flow passage, and a biasing member that biases the spool in a direction from the first pressure receiving face to the second pressure receiving face.</p> |
