Provided is a wrist guard designed to press the radial and ulnar parts of a wrist toward the center of the wrist by means of a compression pad, so as to prevent side effects, such as hand numbness and swelling and effectively provide a fixing force of the wrist, thereby preventing the wrist from being excessively bent and alleviating wrist pain. The wrist guard allows a user to adjust the pressure load on the radial and ulnar parts of the wrist. It is possible to smoothly insert and assemble the pressing member into a coupling body, therefore improving operational feeling, the wrist guard may be stably used, and damage due to interference can be prevented. A stable pulling operation prevents wear and damage. As an excessive pressure load on the radial and ulnar regions is attenuated, the wrist guard is more convenient and comfortable.
