Abstract
A center piece is coupled to a flange member to thereby form a second oil path between an intermediate wall portion of the center piece and the flange portion. A male screw portion is formed on an outer peripheral surface of a cylindrical portion of the center piece, and a nut member in which a female screw portion is formed on an inner peripheral surface is screwed to the male screw portion. Accordingly, the flange member is pressed onto the intermediate wall portion to thereby couple the center piece to the flange member. As a result, the center piece can be coupled to the flange member without causing backlash.
