Vehicle brake hydraulic pressure control unit and method for producing the same

摘要

A vehicle brake hydraulic pressure control unit includes a base body 1 incorporating therein a brake fluid flow path la and an electromagnetic valve 2 which is an assembled part assembled into a mounting hole portion 10A which is formed in the base body 1 in such a manner as to communicate with the flow path 1a. A hole wall of the mounting hole portion 10A has a plastically deformed portion 18 formed by pressing the hole wall in a downward direction of the mounting hole portion 10A. A locking groove 214 for the plastically deformed portion 18 to enter is formed on an outer circumferential surface of the electromagnetic valve 2. An outside diameter of the electromagnetic valve 2 at an upper side of the locking groove 214 is made smaller than an outside diameter of the electromagnetic valve 2 at a lower side of the locking groove 214.
