<p>PURPOSE:To contrive an improvement in sealing performance by preventing the number of component parts from increasing, by making a pair of side plates provided with seals sealing an axial direction and a pair of bottom plates provided with seals sealing a vertical direction into an integrated structure. CONSTITUTION:To fix a sealing device, return caps 4, 4' are fixed to a bearing body 3 and the sealing device 10 is fixed from the bottom side further, which is secured to the return caps 4, 4' with screws. In this case, when a groove 14 adaptable with a bottom plate 12 having a rhombic-shaped cross section is provided on the inside of the bottom of the bearing body 3 and the return caps 4, 4' it is unnecessary to secure the bottom plate 12 particularly either to the bearing body 3 or the return caps 4, 4', and pressing force is applied upwardly to the bottom plate 12 always through the action of the groove 14 as lateral force is applied always to the rhombic-shaped bottom plate 12 from a sliding rail 1.</p> |
