Patent number: 11962227Abstract: An electric actuator of the disclosure includes a motor, a speed reduction mechanism, and a bearing fixed to a motor shaft having an eccentric axis portion. The speed reduction mechanism has: an externally toothed gear, an internally toothed gear, a facing member facing the externally toothed gear, column members protruding from one member of the facing member and the externally toothed gear toward the other member and surrounding the motor axis, and at least one tube member surrounding the column members. The other member has hole portions surrounding the motor axis. The column members are inserted into the hole portions respectively, and support the externally toothed gear to be swingable around the motor axis via an inner side surface of each of the hole portions. The at least one tube member surrounds the column members in the hole portions and is rotatable around a rotary axis passing through the hole portions.Type: GrantFiled: June 7, 2021Date of Patent: April 16, 2024Assignee: NIDEC TOSOK CORPORATIONInventors: Hiroshi Shirai, Kohei Osuga, Kenichi Ozawa
