Abstract
A robot arm () of the present invention includes, as a direct acting extensible/retractable joint (J), an arm section () constituted by an upper structure group () and a lower structure group (). Groups () and (), having an arrangement in which structures are connected in series, partially engage so as to form a direct rigid combined structure, and are separated so as to release the rigid structure. An arm length can be adjusted arbitrarily. Section () can have a plane surface having no gap to prevent entry of a finger/dust. Separation of Groups () and () allows an upper structure () and a lower structure () to rotate around their rotational axes, to realize compact storage inside a robot arm supporting member (). It is thus possible to prevent significantly entry of a finger/dust, and provide a compact direct acting extensible and retractable arm mechanism.
