To provide a cutting device capable of cutting out a concrete block in a short work period by making an inner diameter of a guide hole small.SOLUTION: A cutting device comprises: a loop wire 10 embedded with diamond abrasive grains; a pair of wire guide units 11B guiding the wire 10; and a drive device rotating the wire 10. The pair of wire guide units 11B each include: a support beam 20 extending in a predetermined direction; a support part 21 extending radially toward outside from an outer peripheral surface of the support beam 20; a rotation part 24 provided at a tip end of the support beam 20 and rotatable around a central axis C of the support beam 20 as a rotation axis; and a first guide pulley 23 provided in the rotation part 24 and rotatable on the central axis C of the support beam 20 and around a direction intersecting the central axis C as a rotation axis P.SELECTED DRAWING: Figure 3 【課題】ガイド穴の内径を小さくして、短工期でコンクリートブロックの切り出しが可能な切断装置を提供する。【解決手段】切断装置は、ダイヤモンドの砥粒が埋め込まれた環状のワイヤ１０と、ワイヤ１０を案内する一対のワイヤガイドユニット１１Ｂと、ワイヤ１０を回転させる駆動装置と、を備える。一対のワイヤガイドユニット１１Ｂは、それぞれ、所定方向に延びる支持ビーム２０と、支持ビーム２０の外周面から外側に向かって放射状に延びる支持部２１と、支持ビーム２０の先端に設けられて支持ビーム２０の中心軸Ｃを回転軸として回転自在な回転部２４と、回転部２４に設けられて支持ビーム２０の中心軸Ｃ上でかつ中心軸Ｃに交差する方向を回転軸Ｐとして回転自在な第１ガイドプーリ２３と、を備える。【選択図】図３
