A sliding pin fixing structure of a caliper brake is provided to increase fuel efficiency by reducing drag, and to improve sliding efficiency by automatically centering in assembling the sliding pin with a chamber part in a cylinder arm and an embossed part in the sliding pin. A sliding pin fixing structure of a caliper brake includes a cylinder arm(121) extended at both sides of a cylinder to contact inner and outer brake pads to a disk in operating a piston inside the cylinder, a bolt(122) inserted to a penetration hole(123) of the cylinder arm, and a guide unit(130) with a sliding pin(140). A chamber part(124) is formed in an inner end of the cylinder arm, and a round embossed part(141) is extended in the sliding pin corresponding to the chamber part. Inclination is restricted by naturally centering in assembling the sliding pin with an inner pin hole(131) of the guide unit, and the sliding pin is moved actively in actuating the caliper brake.
