PURPOSE: A guide pin for a robot is provided to reduce uneven wear by rotating a contact portion of the guide pin and the substrate, and to replace the contact portion of the guide pin easily and promptly by releasing the stopper from the column. CONSTITUTION: A guide pin for a robot is composed of a fitting part(202) inserted to an installation hole of a robot arm; a column part(204) integrally extended from the fitting part to the upper part; a contact part(206) fitted around the column part; and a stopper(208) combined with the upper part of the column part to prevent displacement of the contact part. Uneven wear is reduced by rotating the contact part contacted to the substrate, and the contact part of the guide pin is replaced conveniently and promptly by releasing the stopper from the column part.
