Rotary electric shaver

摘要

A rotary electric shaver provided with a plurality of cutter units, each of which has an outer cutter (72) and an inner cutter (84), which rotates while elastically contacting the outer cutter from below. The shaver comprising: a plurality of outer cutter assemblies (70), each of which is made integral with a cutter circumferential rim (74) having the outer cutter of each cutter unit secured thereto and which is movably retained in a mounting port formed in the cutter frame (66), a pushup plate (92) which contacts the outer cutter assembly from below to push up the outer cutter assembly, a cutter retaining plate (90) which is retained by the cutter frame and which is positioned below the pushup plate, and an outer cutter float spring (94) which is compressively interposed between the cutter retaining plate and the pushup plate to impart an upward return tendency to the pushup plate. Each outer cutter can independently move, thus ensuring smooth vertical movement or rocking of the outer cutter and also permitting an increased shaving area.
