  • Patent number: 11519480
    Abstract: An electric actuator 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 arranged facing the externally toothed gear, and column members arranged to protrude from one member of the facing member and the externally toothed gear toward the other member and surround the motor axis. The other member has hole portions arranged to surround 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. At least one of the column members is attached to the one member in a manner of being rotatable around a central axis of the at least one column member.
