Vehicle brake hydraulic pressure control apparatus and method for manufacturing the same

A vehicle brake hydraulic pressure control apparatus includes a base body 1 and a solenoid valve 10 attached to an attachment hole 100 which opens on one surface 1a of the base body 1. A plurality of press-fitting portions 18b, 12b that are press-fitted to an inner peripheral surface of the attachment hole 100 are provided on an outer peripheral surface of the solenoid valve 10 at an interval in a hole axis direction. Contact lengths, in the hole axis direction, between the inner peripheral surface of the attachment hole 100 and two of the press-fitting portions 18b, 12b are different from each other.
