Abstract: A strainer has an inlet for oil; a filter through which the oil that has flowed in from the inlet passes from inside to outside; a first supply port for supplying, to a first oil pump, the oil that has passed through the filter; a second supply port for supplying, to an intermittently driven second oil pump, the oil that has passed through the filter. The second supply port is located more upward than the first supply port; and the filter has a region located below the second supply port.
