摘要： PROBLEM TO BE SOLVED: To reduce a contact resistance that occurs at the contact part between a side plate and an outer rotor or an inner rotor, and decrease the amount of wear between the side plate and the outer rotor or the inner rotor.SOLUTION: Recesses 72d are formed in an area (outer tooth passing area) between a line through which the tooth tip part of an outer tooth part 52a in an inner rotor 52 passes and a line through which the bottom of the tooth passes, in an end face of a second side plate 72. Thereby, when the recesses 72d are brought into communication with gaps 53, the brake fluid contained in the gaps 53 is supplied in the recesses 72d. Accordingly, the brake fluid can be made to intervene between the second side plate 72 and the inner rotor 52, and the brake fluid functions as lubricating oil. Thereby, the frictional resistance of the contact part between the second side plate 72 and the inner rotor 52 can be reduced, and the amount of wear can be decreased.

摘要： PROBLEM TO BE SOLVED: To suppress a reduction in slide resistance between a side plate and an outer rotor or an inner rotor, and to suppress fluid leakage from between them.SOLUTION: An end face 72b of a second side plate 72 on which a mechanical seal is applied includes: a first face 72ba inclined with respect to a center axis Y; and a second face 72bb of which inclination angle is changed to be directed in a radial direction with respect to the first face 72ba. By forming such a second face 72bb, a clearance formed between the end face 72b and an outer rotor 51 can be narrowed, and an amount of a brake liquid intruding into the clearance can be reduced. With this configuration, the flow resistance between the second side plate 72 and the outer rotor 51 can be increased; the brake liquid hardly flows; and thus the leakage of the brake liquid from a high-pressure region to a low-pressure region can be suppressed.
