PURPOSE: To provide an inexpensive guide roller having simple structure in a wire saw. CONSTITUTION: A pair of synthetic-resin-made ring members 25 and 25 are made to abut with each other to be fixedly mounted to a roller peripheral surface by a guide roller for guiding a running wire 1, and a pair of ring members 25 and 25 are fastened in an abutting direction to be fixed by a pair of presser members 26 and 26 from both the end surfaces of the roller to form the guide groove of the wire 1 between the pair of ring members 25 and 25. |
