A computer mouse structure for preventing foreign materials from accumulating on an X-axle and a Y-axle in the computer mouse includes two scraper seats located on an inner side of a lower shell of the mouse on one side of the X-axle and the Y-axle opposite to a track ball which is in contact with the X-axle and the Y-axle. Each of the scraper seats has a scraper which is spaced from the axle at a selected gap to remove the foreign materials attached to the axle when the foreign materials reach the scraper during rotation of the axle.
