The housing, the fixed disk, and the rotary disk respectively have a plurality of communication paths (20, 30, 40, 50), and the communication paths are connected accompanying the rotation of the rotary disk, whereby the flow paths of a fluid are formed. Seal members (17, 18) which suppress leakage of the fluid at least between the fixed disk and the rotary disk are respectively provided in the flow paths. The leading end section (15a) of the rotary shaft is provided to be able to contact and engage with the fixed disk, and the fixed disk is configured to be able to reciprocate in the axial direction by contacting and engaging with the leading end section of the rotary shaft.
