Abstract
A rotor is placed on one axial side relative to a passage hole forming portion at an inside of a housing. A differential pressure device is placed on the one axial side relative to the rotor and has a pressure chamber. The housing has: a one-side space that is placed on the one axial side relative to the rotor; and at least one other-side space that is placed on another axial side, which is opposite to the one axial side, relative to the passage hole forming portion. The differential pressure device generates an urging force that urges the rotor against the passage hole forming portion by a differential pressure between a pressure in the pressure chamber and a pressure in the one-side space in a case where a pressure in the at least one other-side space is higher than the pressure in the one-side space.
