Provided is a moving unit (1) that enables a movable body (41) to be smoothly moved along guide tracks (2) for guiding the movable body (41) across joints between a plurality of track rails (21) arranged in series so as to serve as the guide tracks. The moving unit (1) includes: the pair of guide tracks (2) laid in parallel to each other; a plurality of moving blocks (3) being two or more moving blocks (3) assembled to each of the guide tracks and being freely movable along the guide tracks; and the movable body (41) fixed to the moving blocks. The track rails (21) arranged in series serve as the guide tracks, and each have a guide surface (25) formed along a longitudinal direction of each of the track rails. The moving blocks (3) each include contact elements (31) configured to travel on the guide surface while passing across joint clearances (L) each being formed between the track rails arranged in series. When one of the moving blocks (3) is positioned at any one of the plurality of joint clearances (L) formed on the pair of guide tracks (2), another of the moving blocks is not positioned at another of the joint clearances. |
