Abstract: A linear actuator unit has a slide plate which is allowed to freely move along the outer rail while causing a cover to retreat. The linear actuator unit includes: an outer rail, which is formed into a cylindrical shape, and includes the slit-opening portion formed along an axial direction thereof; the slide plate (3), which is coupled to an inner block in the hollow portion through the slit-opening portion; a cover belt, which is tensioned between both ends in a longitudinal direction of the outer rail so as to cover the slit-opening portion; a belt-guiding member, which separates the cover belt from the outer rail correspondingly to movement of the slide plate; and a seal member, which seals between the belt-guiding member and the cover belt and between the belt-guiding member and the outer rail.

Abstract: PROBLEM TO BE SOLVED: To provide a turning structure capable of easily and inexpensively producing a structure of a large turning diameter, easy to carry, and capable of optimally distributing load applying capacity in 360° around the turning center in response to various use of the turning structure. SOLUTION: This turning structure is composed of a lower structure, an upper turning body turnably arranged to this lower structure, and a turning bearing mechanism interposed between these lower structure and upper turning body. The turning bearing mechanism is composed of a plurality of circular arc-shaped track rails of constant curvature, and is composed of an endless annular ring-shaped fixed ring of continuously arranging these track rails on the lower structure, and at least three units or more of slide blocks installed in the fixed ring via a large number of rolling elements and freely movable along the fixed ring in a state of carrying the upper turning body.
