Disclosed is a guide roller wherein bearings are held in a housing, and liquid mixed with abrasive grains is prevented from entering the interior of the housing through a small hole, thereby improving service life. The guide roller is configured to comprise a housing wherein the bearings are held in the housing, and the housing has a shaft hole wherein a support shaft is inserted that is installed upon the bearings. The shaft hole is formed to have a tapered wall, and the diameter of the hole decreases continuously toward the interior of the housing.
