An electric actuator includes a shaft member, a nut member, a power transmission member, and a guide portion. A spiral groove is formed on an outer circumference of the shaft member. The nut member is fitted onto the shaft member. A power transmission member is disposed between an inner circumference of the nut member and the groove. The guide portion is configured to guide linear motion of the shaft member. Rotation of the nut member about the shaft member by means of a rotational driving force of an electric motor results in the linear motion of the shaft member. The guide portion includes a rotating mechanism portion configured to rotate the shaft member about an axis when the shaft member is in the linear motion.
