A vehicle brake hydraulic pressure control unit includes a base body incorporating therein a brake fluid flow path and an electromagnetic valve which is an assembled part assembled into a mounting hole portion which is formed in the base body in such a manner as to communicate with the flow path. A hole wall of the mounting hole portion has a plastically deformed portion formed by pressing the hole wall in a downward direction of the mounting hole portion. A locking groove for the plastically deformed portion to enter is formed on an outer circumferential surface of the electromagnetic valve. An outside diameter of the electromagnetic valve at an upper side of the locking groove is made smaller than an outside diameter of the electromagnetic valve at a lower side of the locking groove.
