The carrier 20 is fixed to the vehicle body, and the outer pad plate 40, And an adhesive padding 50 attached to the outer surface of the adhesive padding 50.

The caliper housing 10 is provided with a cylinder 12 in which the piston 13 is housed and a pair of fingers 14 for operating the outer pad plate 40. The cylinder 12 is formed at a rear portion of the caliper housing 10 so that braking hydraulic pressure formed in a master cylinder (not shown) is transmitted to the caliper housing 10, And is configured to bend in a downward direction from the front portion of the outer pad plate 10 and to press the left and right portions of the outer pad plate 40.

The disk-shaped disk is fixed to the wheel of the vehicle so that a part of the outer circumferential surface thereof rotates while maintaining a constant gap between the pair of pad plates 30, 40.

The pair of pad plates 30 and 40 are spaced apart from the carrier 20 fixed to a knuckle (not shown) of the vehicle body so as to be movable in the horizontal direction.

The pair of pad plates 30 and 40 are distinguished by an inner pad plate 30 having an inner pad 31 attached to the inner surface thereof and an outer pad plate 40 having an outer pad 41 attached thereto. The inner pad plate 30 is disposed so as to be in contact with the front end surface of the piston 13 whose outer surface moves forward and backward so as to press one surface of the disk during the braking operation, So as to press the other surface of the disc during the braking operation.
