Abrégé

A support and guide device is configured so that, even if there are gaps at the joints between track rails (4) which constitute a guide track (1), the support and guide device is capable of enabling a movement block (2) to smoothly transfer from one track rail (4) to another track rail (4), the movement block (2) moving along the guide track (1). The support and guide device is provided with the serially arranged track rails (4) and a movement block (2) which is capable of moving along the guide track (1) while sequentially transferring between the track rails (4). Each of the track rails (4) has a guide surface (41) provided along the longitudinal direction, and the movement block (2) has a contact (3) which travels on the guide surface (41) of the track rail (4). Auxiliary slide surfaces (5) are provided at the longitudinal opposite ends of each of the track rails (4) so as to be side by side with the guide surface (41) and so as to be tilted relative to the guide surface (41). The movement block (2) is provided with leading slide sections (9) which are configured so that, when the movement block (2) reaches a longitudinal end of each of the track rails (4), a leading slide section (9) faces the auxiliary slide surface (5) of the track rail (4).

Provided is a movement unit (1) in which, in a case where a plurality of track rails (21) disposed in series constitute a guide track (2) for guiding a movable body (41), it is possible to ride across the joints of the track rails and move smoothly over the guide track. The movement unit is provided with the following: a pair of the guide tracks (2) laid in parallel with each other; a plurality of movement blocks (3) at least two of which are assembled to each guide track and that freely move along the guide tracks; and the movable body (41) fixed to the movement blocks. The guide tracks are provided by disposing in series the track rails (21) on which a guide surface (25) is formed along the longitudinal direction. Meanwhile, the movement block (3) has a contact (31) that, while running on the guide surface, passes joint-unit gaps (L) of the track rails that are disposed in series. When, in relation to the plurality of joint-unit gaps (L) included in the pair of guide tracks (2), the movement block (3) is positioned over any one of the joint-unit gaps, no other movement block is positioned over any other joint-unit gaps.

The present invention is to provide a simple linear stopper which is capable of stopping the movement of an object in a reliable manner with a simple structure. The present invention is characterized by comprising: a stopper body has an inclined surface formed thereon, with a wedge-like space being constructed between the inclined surface and a surface of the guide member with a gap decreasing gradually toward one side of an extending direction of the guide member; rolling elements that are arranged in said wedge-like space so as to be rollable therein; and rolling element pressing means that presses the rolling elements in a direction to bite into the wedge-like space, so that the rolling elements are forced into pressure contact with the surface of the guide member and the inclined surface of the stopper body; wherein a one-way stopper mechanism is provided which restricts the relative movement of the stopper body with respect to said guide member toward a side at which the gap in the wedge-like space is large, due to a biting action caused by the rolling contact of the rolling elements in said wedge-like space, and allows the relative movement of the stopper body with respect to said guide member toward a side at which the gap in the wedge-like space is small, due to the sliding contact of the rolling elements in said wedge-like space.
