PURPOSE: To smoothly pass hair through and to satisfactorily keep the cutting efficiency bar forming a raising projection standing up in the overlapping direction of a fixed blade and a movable blade, extending a small projection, whose tip reaches a movable blade tip part, from the projection for raising and positioning the tip part of the fixed blade within the groove formed between the small projection and the main body of the comb piece.

CONSTITUTION: The projection for raising 32 at the comb 31 is positioned in front of the blade of the fixed blade 21, the small projection 33 covers the tip part of the blade 21 and its tip reaches near the tip of a movable blade 22. At an attachment 3, the projection 33 extended through the projection 32 from the piece 31 guides hair H in an arranged state from entering into the blade groove of the blade 21 to a position of cutting hair H, namely a position where the blade 22 comes into slidable contact with the blade 21, to be cut. Consequently, hair H temporarily introduced into the blade guide of the blade 21 is surely cut without entanglement to smoothly pass through and improve cutting efficiency.
