  "textContent": "To prevent occurrence of contamination at the time of press-inserting and fixing a guide ring that guides sliding of a piston. In a brake hydraulic pressure control apparatus () including: a base body () having a cylinder hole (); a piston () fitted to the cylinder hole () in a freely slidable manner; and a guide ring () attached to an opening () of the cylinder hole () and guiding sliding of the piston (), the guide ring () has: a flange portion () in a lower surface () opposing the cylinder hole (), the flange portion (8) expanding in a radial direction of the guide ring (); and bulged portions () arranged at equally-spaced intervals to an outer circumferential surface () of the guide ring () and each bulged outward in the radial direction of the guide ring () when compared to the flange portion (). When seen from a cross section in an axial direction (Ax) of the guide ring (), each of the bulged portions () has a tapered portion () expanding in the radial direction of the guide ring () from the lower surface () toward an upper surface () of the guide ring ().",
