Abstract

To provide a hair cut unit of a reciprocation type electric shaver.SOLUTION: A hair cut unit of a reciprocation type electric shaver includes an outer blade, an inner blade, a support, and a holder. The outer blade includes an outer blade arc-shaped wall and two opposite outer blade long walls, wherein the support supports the inner blade, and the holder includes two opposite holding walls. The outer blade long walls are provided with follow holes, at least the one support penetrates through the follow holes, and the outer blade long walls are movable along a support penetrating through the follow holes. When the cut unit receives non-uniform pressure from skin, the outer blade arc-shaped walls follow the moving outer blade long walls, can include the inner blade without being deformed, and accordingly can maintain high hair cut efficiency even at the time of actual use.SELECTED DRAWING: Figure 5
