Patent ID: 8820858

Claim:
A brake hydraulic pressure control apparatus for a vehicle, the apparatus comprising: a base member; a control housing including a storage space for storing an electromagnetic valve provided on one face of the base member and a coil assembly to be mounted onto the electromagnetic valve; and a pump driving motor provided on a back face opposed to the one face of the base member , wherein the base member are provided with: two housing mounting penetration holes wherein each of the housing mounting penetration holes is so formed as to penetrate from the one face to the back face and through which a housing mounting screw for fixing the control housing is to be inserted; two motor mounting holes, wherein each of the motor mounting holes is opened up in the back face and into which a motor mounting screw for fixing the motor is to be inserted; and a rotation shaft storage hole which is opened up in the back face and into which a rotation shaft of the motor is to be stored, wherein the housing mounting penetration holes are disposed point-symmetrically with respect to the center of the rotation shaft storage hole, wherein the motor mounting holes are disposed point-symmetrically with respect to the center of the rotation shaft storage hole and are disposed at different positions from positions where the housing mounting penetration holes are disposed, and wherein a peripheral wall portion of the control housing that defines the storage space is formed to have a quadrangle frame shape, of the four sides of the peripheral wall portion, in a pair of sides opposed to each other, there are formed flange portions respectively projecting outwardly, housing fixing holes are formed in the flange portions so as to be threadedly engageable with the housing mounting screws, a seal member is interposed between the one face of the base member and the peripheral wall portion, the seal member includes a quadrangle frame shaped peripheral edge portion extending along the peripheral wall portion and a plurality of belt-shaped tongue portions respectively projecting from their associated sides of the peripheral edge portion inwardly, the tongue portions include first tongue portions respectively formed in a pair of sides of the seal member corresponding to the pair of sides of the peripheral wall portion which are adjacent to the housing fixing holes, and the tongue portions are held between the base member and the coil assembly only at positions where the first tongue portions are formed.
