Embodiment Construction

[0028] 1 to 3 show a hydraulic unit 1 for a vehicle as a hydraulic unit according to an embodiment of the present invention, which is used in a brake control device. The casing 10 of the hydraulic unit 1 has two planar portions 11 and 12 adjoining therebetween at a predetermined angle (90 degrees in the present embodiment). FIG. 1 shows a state in which a protective tape 20 bonded to a hydraulic unit 1 for a vehicle is cut by a laser beam for each separation portion (indicated by 21 ). The casing 10 of the hydraulic unit 1 for a vehicle has two planar portions 11 and 12 adjoining at a predetermined angle (90 degrees in the present embodiment). As shown in dotted lines in FIGS. 1 to 3 , each of these planar portions 11 and 12 is formed with at least one opening (also referred to as an aperture, indicated at 13 and 14 , respectively).

[0029] A protective tape 20 is adhered to cover the respective openings 13 and 14 on the aforementioned case 10 . The protective tape 20 is a ...

Abstract

A hydraulic unit is provided with a housing having two planar portions neighboring at a predetermined angle between them. At least one opening is formed on each of the planar portions. For example, one opening and at least two openings are formed on the two planar portions, respectively. A protective tape is adhered to the two planar portions of the housing for covering each opening formed on each of the two planar portions. The protective tape is cut by a laser beam, for example, to be separated into at least each one of a part for covering one opening and a part for covering at least two openings.

Description

technical field [0001] The present invention relates to a hydraulic unit such as a hydraulic unit for a vehicle, and particularly relates to a hydraulic unit in which a housing having at least one opening is formed and a protective tape is adhered to cover the opening. Background technique [0002] Generally, a hydraulic unit such as a hydraulic unit for a vehicle has at least one opening (hole) formed in its casing, and a rubber plug is inserted into the opening to prevent foreign matter from entering through the opening, or a protective tape is attached to cover the opening. Regarding the hydraulic unit for vehicles, Japanese Patent Document Laid-Open No. 2002-339903 discloses such a technology that "a protective tape can be bonded to the outer surface of the housing to simultaneously cover at least two openings of the piping connection port", and It is explained as follows. As stated in the abstract, the first feature is to protect the opening of the pipe connection port...
