Document Type and Number:
WIPO Patent Application WO/2015/170884
Kind Code:
A1
Abstract:
The present invention relates to a roller. More specifically, a rotary shaft of the upper part of a rolling wheel, having an inclined surface formed along the circumference of an outer diametral surface thereof, is inserted into at least one coupling groove formed on a transfer bracket, a thrust member is provided at the upper part of the rotary shaft so as to allow a thrust load to be concentrated on the upper end of the rotary shaft or the thrust member, and a radial member is provided at the inner surface of the coupling groove and the rotary shaft positioned at the lower part of the thrust member, thereby supporting a radial load. Therefore, provided is the roller enabled to resolve the problem of reduced durability of the thrust member and the radial member due to: a biased vertical load and lateral thrusting, which act on the rotary shaft or the rolling wheel, by improving a structure so as to efficiently absorb, disperse, and share the thrust load and the radial load; and foreign materials, moisture and the like by configuring the thrust member and the radial member as a sealed structure.
