Claim 9:
10. A caliper brake comprising:
a carrier fixed to a vehicle body;
a caliper housing installed on the carrier to advance and retreat;
a guide rod having one end fixed to the caliper housing and the other end slidably coupled to a guide hole provided on the carrier to slidably couple the caliper housing to the carrier; and
a boot mounted on the guide rod and the carrier to prevent foreign substances from being introduced into the guide hole,
wherein the boot comprises a first coupling part coupled to the guide rod at one end of the boot, and a second coupling part coupled to the carrier at the other end of the boot,
wherein the second coupling part is provided with one or more elastic protrusions provided to be in contact with an outer surface of the guide rod so that a reaction force is generated by the guide rod moving together with the caliper housing during braking,
wherein an inner diameter of the elastic protrusion of the second coupling part facing the guide rod is gradually decreased toward an outside of the guide hole, and
wherein a surface of the elastic protrusion of the second coupling part facing the guide rod is obliquely slanted in only one direction such that an elastic force of the elastic protrusion is generated in a direction oblique to a radial direction of the boot.
