The linear motion rolling guide unit of this invention makes the total lengths of the retainer plates, which support the cylindrical rolls, longer than that of the casing so that the retainer plates can be inserted into the end caps for assembly. This simplifies the construction and reduces manufacturing costs. The retainer plates each comprise retaining portion formed with two or more rows of slots that support the cylindrical rolls in such a way as to allow the rotating motion of the rolls, a bent portion which is bent away from the track rail, and locking portions projecting from both ends of the bent portion. The locking portions fit into recesses in the end caps, the bent portion fits into grooves in the end caps, and the upper end portion of the retainer fits into grooves in the end caps.
