The present invention relates to a cutting blade assembly of a rotary drum type electric razor. In the cutting blade assembly of the rotary drum type electric razor which has an ON/OFF switch formed at a front and is rotated at a high speed by being delivered with driving force of a motor driven in accordance with operation of the ON/OFF switch by a power delivery unit, the present invention relates to the cutting blade assembly of the rotary drum type electric razor, which includes: a number of cutting blades (100) which are formed lengthily in a plate type in a longitudinal direction, and have a number of insertion holes (110) formed at an inner diameter side, and have a hooking groove (120) formed at both ends; a number of support pieces (200) on a disc which have a number of cutting blade combining grooves (210) which are formed along an outer circumference and are formed in ㅓ shape by forming an insertion protrusion (212) to be combined with the insertion holes (110) of the cutting blade (100) in a corresponding quantity to the insertion holes, and have a hexagonal hole (220) at a center; a drive shaft (300) which has a circular shaft part (310) which is axially combined with the power delivery unit and is formed at both ends, and includes a hexagonal shaft part (320) inserted into the hexagonal hole (220) formed at the center of the support piece (200) among the circular shaft part (310); and a fixed piece (400) which has a hooking frame (410) combined with the hooking groove (120) of the cutting blade (100), and has a through-hole (420) penetrated by the circular shaft part (310) of the drive shaft (300). |
