Patent ID: 7124657

Claim:
An electric actuator, comprising: an actuator body which is a unitary four-sided rectangular tube all sides of which are integrally and seamlessly joined to each other and having two pairs of opposing surfaces, and which has a slit formed to extend by a predetermined length along an edge of said rectangular tube, said edge being defined as an intersection of two of said sides of said four-sided rectangular tube; a driving source which is connected to an end of said actuator body; a driving force-transmitting mechanism which is arranged in a space surrounded by said actuator body and which transmits a driving force of said driving source; and a slider which reciprocates along said slit of said actuator body by means of said driving force transmitted from said driving force-transmitting mechanism, wherein said slider comprises a plate-shaped portion passing through said slit and extending a distance beyond a side surface of said actuator body, said plate-shaped portion lying in a horizontal plane parallel to a horizontally disposed base of said actuator body, and wherein said actuator body is formed to be flat so that a dimension of said actuator body in a horizontal direction is larger than a dimension of said actuator body in a height direction.
