A ROLLER DEVICE FOR DISPLACEMENT OF RAILROAD SWITCHING RAILS' comprising a basic structure (10), provided in its end with a stylized horizontally-S-shaped laminar locking rib (1), said structure (10) being centrally provided with a pair of trapezium-shaped longitudinal plates (2) parallel to each other, each of said longitudinal plates having in its mid-portion a pair of rectangular cuts (3) extending from the edge to half the height thereof. The ends of the shafts (4) of corresponding rollers (5) being attached to the said cuts, allowing the rotational movement of the rollers (5) around their own axis and relatively to the said longitudinal plates (2) which support them. On the opposite end of the basic structure (10), it is defined a L-shaped laminar rib (8), which is mounted on a transversal support (11) defined by a U-shaped folded plate with horizontal extents (11a), there being provided oblong holes (11b), through which through-bolts (11c) are passed, from this transversal support (11) in relation to the sleepers (D) of the railroad track. The L-shaped end (8) is provided with a pair of through-holes (8a), through which goes the through-bolts 8b, which are fixed to the transversal support (11), each of the said through-bolts (8b) going through and being involved by a steel spring (9) with its ends directly contacting the lower face of the L-shaped end (8) and the upper face of the mid-portion of the support (11), exerting a separation force between the last said components. The through-bolts (8b) are prevented from turning relatively to the L-shaped end (8) and support (11) by a small horizontally-L-shaped lock (8c), which is secured by bolts (8d) to the respective through-bolts (8b).
