PROBLEM TO BE SOLVED: To provide a guide pulley device for a wire saw capable of carrying out easy exchange work of a guide pulley in a cutting end period. SOLUTION: The guide pulley device for the wire saw is provided with an attachment base 10 temporarily fixed to an end face of a body 1 to be cut, a hollow square attachment box 12 vertically protruding from a front face of the attachment base 10, and a cross sectionally quadrangular attachment arm 14 which can be fit in the attachment box 12 and temporarily fixed to it. The attachment arm 14 is provided with a first pulley 18 rotatably attached via a spindle 16a arranged vertically from an intermediate part of a one side face, and a second pulley 20 rotatably attached via a spindle 16b arranged vertically from a tip of another side face adjacent to the side face attached with the first pulley 18. The first and second pulleys 18 and 20 mutually comprise a crossing angle of 90 deg., and they are positioned to have the same tangent mutually so that the wire saw 7 wound around both pulleys can be transferred. |
