The blade member (15) is arranged between the blade base member (16) and the top member (17). The cutting edge (13a) of each blade (13) is exposed through the top member (17). A blade supporting portion (24) provided in the blade member (15) has a plurality of step plates (29) arranged in a blade arrangement direction (Z), which is orthogonal to the direction in which the cutting edge (13a) extends. A reinforcement plate portion (33), which increases the rigidity of the step plate (29), is provided while being bent from the step plate (29). The blade supporting portion (24) is also provided with a bridge portion (30) for mutual coupling. |
