Patent number: 6581289Abstract: An inner cutter for an electric rotary shaver, the inner cutter comprising a cutter supporting member and an inner cutter body. The cutter supporting member has a ring-form body formed in a shape of a flat plate and is provided with a plurality of upright supporting portions that rise from an outer-circumferential edge of the ring-form body and are lined up side by side. The inner cutter body is formed on the tip end of each one of the upright supporting portions. Gaps are formed between adjacent upright supporting portions, and ribs are provided between the adjacent upright supporting portions, thus allowing cut hair to be discharged out of the inner cutter through openings defined by the adjacent upright supporting portions and ribs.Type: GrantFiled: July 25, 2001Date of Patent: June 24, 2003Assignee: Izumi Products CompanyInventor: Tsuyoshi Nakano
