PURPOSE: A structure for a caliper of a brake system is provided to improve energy transfer efficiency by engaging mediums for changing rotary power generated from a motor into a rectilinear motion by right-triangle teeth. CONSTITUTION: In a structure for a caliper of a brake system for converting rotary power of a motor(11) into a rectilinear motion, the caliper is composed of a motor tooth unit(12) connected with the motor and formed with first right-triangle shaped teeth(13) at the end; a piston tooth unit(16) having second right-triangle shaped teeth(14) corresponding to the first teeth of the motor tooth unit, one end engaged with the motor tooth unit, and first threads(15) formed on the outer peripheral surface; and a piston(19) having an insertion groove(17) fitted with the outer peripheral surface of the piston tooth unit and second threads(18) formed on the inside of the insertion groove and engaged with the first threads of the piston tooth unit.
