Abstract

A base of a brake fluid pressure control device for a vehicle can cope with various brake line connection structures and realizes weight reduction. An extension part (116) guarantees a sealing width (W1) for circumferential 360 degrees, so that the sealing performance can be favorably maintained. The extension part (116) is shaped as a flange or eaves, so that the design can make the base (40) lightweight compared with the design of overall extension of a motor installing surface (108) or shell installing surface (109).

Description

technical field [0001] The present invention relates to a base body of a brake fluid pressure control device for a vehicle and a brake fluid pressure control device for a vehicle including the base body. Background technique [0002] As a brake fluid pressure control device, for example, the technique disclosed in (Japanese) Patent No. 5724941 (hereinafter referred to as Patent Document 1) is known. In the brake fluid pressure control device disclosed in Patent Document 1, a wheel cylinder oil port and a brake piping mounting seat surface are formed on one surface of a substantially rectangular base. [0003] In the structure like Patent Document 1, since it is necessary to secure a mounting seat surface, it is difficult to reduce the weight of the base. [0004] However, as the connection structure of the brake pipe, for example, a flare type using a flare pipe and a banjo type using a banjo are known, and therefore a structure corresponding to various connection structure...
