PROBLEM TO BE SOLVED: To increase the stiffness of a blade body support part and suppress the deformation of the blade body support part, thereby maintaining shaving performance even when the plate thickness of the blade body support part is set to such a degree that the bending of the blade body support part and the welding of blade bodies to blade body placement parts are facilitated in a structure for supporting the blade bodies in a razor head.SOLUTION: A replaceable blade includes: a blade member 15 including blade bodies 13; a blade base member 16 located on the back side of the replaceable blade; and a top member 17 located on the front side of the replaceable blade. The blade member 15 is arranged between the blade base member 16 and the top member 17, and blade edges 13a of the blade bodies 13 are exposed on the top member 17. A blade body support part provided in the blade member 15 includes a plurality of step plates 29 arranged in a parallel arrangement direction Z of the blade bodies which is orthogonal to the extension direction of the blade edges 13a. Reinforcement plate parts 33 for increasing the stiffness of the step plates 29 are provided so as to be bent from the respective step plates 29. In addition, bridge parts 30 for connecting the step plates 29 with each other in the parallel arrangement direction Z of the blade bodies are provided so as to be arranged side by side with shaving waste elimination holes (through-holes 31) in the extension direction of the blade edges 13a. Since the reinforcement plate parts 33 are provided on the respective step plates 29 in addition to the bridge parts 30, even when, for example, the plate thickness of the blade body support part is set to such a degree that the bending of the blade body support part and the welding of the blade bodies 13 to the step plates 29 are facilitated, the stiffness of the step plates 29 is increased to suppress the deformation of the blade body support part, and shaving performance can be thereby maintained. |
