Abstract: In this rod-less cylinder equipped with a guide mechanism (32), the guide mechanism (32) has: a first rail member (34), which is attached to the sidewall of a cylinder tube (2), has an inner rolling groove (34a), and is composed of alloyed steel; a second rail member (36), which is attached to a protrusion (31) of a slider (27), has an outer rolling groove (36a), and is composed of alloyed steel; a guide path (38a) provided in the protrusion of the slider and extending parallel to the second rail member; a connection member (39) having a connection path (39a) that connects the guide path and the inner rolling groove; and a plurality of rolling bodies (43) accommodated within an endless circulation path (42) formed of the inner rolling groove, the outer rolling groove, the guide path, and the connection path.

Abstract: A magnet-type rodless cylinder (1) is provided with a guide mechanism having an outer rolling groove (26), an inner rolling groove (29), a cylinder body (32), a pair of connection paths (34) for connecting an area between the outer rolling groove and the inner rolling groove with the cylinder body, and a plurality of steel balls (36) that can roll within an endless circuit (35) formed of the cylinder body, the connection paths and the area between the outer rolling groove and the inner rolling groove, wherein the connection paths (34) are formed at a pair of inner members, i.e. return caps (33), disposed on the inner sides of metal end plates (12) that are attached to the front and rear ends in the sliding direction of a sliding body (4).
