Abstract
An actuator device includes a housing having a bore and an internal moving body movable within the bore in the direction along the center axis of the bore. The housing is composed of two housing members which divide the housing along the center axis. An inner surface which forms a part of the wall of the bore and two slit surfaces on both sides of the inner surface are formed on each of the housing members. When two housing members are coupled to each other by fastening the longitudinal portions of the housing members by end members, two slits extending along the entire length of the housing are defined by the slit surfaces of two housing members. Since the respective housing members have relatively simple cross sectional shapes, the housing members can be easily produced, by an extrusion process or a drawing process, at low cost. Further, since two slits are provided on the housing, an external moving body can be connected to the internal moving body by two driving members. Thus, the external force exerted on the external moving body is distributed to two driving members, whereby the strength of the actuator device is increased.
