A technical problem of the present invention is to provide a seal mounting structure of a caliper brake for a vehicle, minimizing a dragging phenomenon and preventing damage to a seal in advance even if a little brake fluid is used. To achieve this, the seal mounting structure of a caliper brake for a vehicle of the present invention, wherein a seal is mounted between a piston and a cylinder, comprises: a seal mounting groove formed in a portion in contact with the piston of the cylinder; a front end wall forming a front end boundary portion of the seal mounting groove based on the direction wherein the piston is pressurized; a rear end wall forming a rear end boundary portion based on the direction wherein the piston is pressurized; and a bottom surface forming the bottom of the seal mounting groove. The front end wall includes: an inner side surface forming a portion with which the seal is in contact; and an end surface forming a portion with which the piston is in contact. A corner between the inner side surface and the end surface is cut off as a convex round shape. |
