- the plunger guard 1612 may be formed in a tapered shape in which the thickness in the y-axis direction decreases toward the front. That is, a side surface of the plunger guard 1612 may have a triangular cross section. As the plunger guard 1612 becomes thinner toward the front, the area for cleaning the shaving blade 110 can be preserved even when the razor cartridge 12 is pivoted at its maximum angle, and the plunger guard 1612 has a constant thickness. An advantage is that the razor cartridge 12 can be pivoted at a greater angle compared to when it is extended.
