Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gear edge cut-off tool and a gear edge cut-off device, which are able to suppress variation in the cut-off amount of a side edge of a gear.SOLUTION: When a first main plane 15X (rake surface) of a first cutting blade part 21 capable of cutting off a side edge 92B of a gear 90 is formed into substantially the same shape as that of an engagement surface 93B of a gear 90, and a gear edge cutting tool 10 and the gear 90 relatively moves, the gear edge cut-off tool 10 of the present invention can suppress the displacement amount of a crossing angle δ between the first main plane 15X and the engagement surface 93B.SELECTED DRAWING: Figure 12 【課題】ギヤのサイドエッジの切除量のばらつきを抑えることができるギヤエッジ切除ツール及びギヤエッジ切除装置を提供する。【解決手段】本発明のギヤエッジ切除ツール１０には、歯車９０のサイドエッジ９２Ｂを切除することが可能な第１切削刃部２１の第１主平面１５Ｘ（すくい面）が歯車９０の噛合面９３Ｂと略同形に形成され、ギヤエッジ切除ツール１０と歯車９０とが相対移動するときに、第１主平面１５Ｘと噛合面９３Ｂとの交差角δの変位量を抑えることができる。【選択図】図１２
