A caliper brake comprising two pads formed and a carrier on which a support groove is mounted, wherein the spring pad is disposed between the two pads and the carrier, the guide portion engaging with the support groove; And it protrudes from one side of the guide portion extends toward the disk, and the elastic member for restoring the pad spaced apart from the inner surface of the guide portion as it extends toward the disk.

As described above, the conventional spring pad is advanced while the pad pushes the protruding member and the extending member of the elastic member for restoring the pad, and then is returned to its original position by the restoring force of the elastic member. In other words, when the pad pushes the elastic member, the cross section has a 'U' shape, and when the pad is in place, the pad has a 'V' shape. In this case, when the brake is deeply bright while driving, there is a difficulty in maximizing the instantaneous restoring force of the extension member which is in contact with the pad because the pad is pressed deeply at the end side of the elastic member.

In addition, the conventional spring pad has a problem in that the flow of the spring pad installed in the carrier is generated by the impact and external shock generated during use after a certain time.

The present invention for solving the above problems is that the spring is coupled to the inner and outer sides of the carrier, it is possible to stably install the spring on the carrier, the elastic portion is provided to be inclined downward from the upper side of the spring to maximize the restoring force of the brake pad It provides a caliper carrier and spring coupling structure.

In the caliper carrier and the spring coupling structure of the present invention for solving the above problems, the coupling piece protrudes on both sides, the first and second ground surfaces are perpendicular to the upper and lower portions of the coupling piece, and orthogonal to the second ground surface. A third support surface formed to face each other, the carrier including fixed surfaces on both sides of the inner surface; Insertion grooves formed of an upper surface to be fitted to the upper side of the coupling piece of the carrier, the front surface bent from the upper surface, the lower surface bent from the front surface, and formed on the upper and lower portions of the insertion groove and the first, The first and second contact surfaces in close contact with the ground surface, the guide portion perpendicular to the second contact surface and seated on the third support surface of the carrier, and the brake pad along the inner side and the guide portion of the second contact surface. An elastic portion consisting of a sliding groove for inducing the forward and backward, and the connecting portion is bent forward from the upper end of the first contact surface and the bending portion is bent downward from both sides of the connecting portion, the pressing guide portion extending to the bent portion And a spring including a support part fixed to both sides of the fixing surface while being inclined backward to the lower portion of the first contact surface; The inner surface of the second contact surface is composed of a locking step to prevent the separation of the brake pads.

Therefore, the caliper carrier and the spring coupling structure of the present invention is the spring is coupled to the inside and outside of the carrier to be able to install the spring on the carrier stably and the elastic portion is provided to be inclined downward from the upper side of the spring contact the elastic portion There is an effect that can maximize the restoring force of the brake pad generated by.
