SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the conventional art, and it is an object of the present invention to provide a roller and a roller, And a caster, thereby increasing the stress on the load and increasing the stress on the load that improves the rolling property.

According to an aspect of the present invention, there is provided a wheel structure for increasing stress on a load according to an embodiment of the present invention includes a pedestal 110 coupled to a lower portion of a movable furniture, a supporter 130 for fastening the roller, A caster frame (100) comprising a fixed bar (150) for connecting and fixing the pedestal and the support, and a bearing (170) fastened between the pedestal and the support and between the support and the fixed bar;

A roller 300 fastened to the caster frame by an axis to smoothly move movable furniture or the like;

And a gap adjusting compression spring (500) which is fastened to the inner side of the roller so as not to allow clearance between the castor frame and the roller so that it does not flow when the roller rotates.

The roller (300) has a through hole (310) through which the shaft (700) is inserted and in which the interval adjusting compression spring (500) is inserted;

The bearing fastening step 330 is formed on both sides of the through hole so that the bearing 350 can be fastened. The bearing fastening step 330 is fastened to the caster frame by the shaft 700 and fixed to the lower part of the portable furniture.

The gap adjusting compression spring 500 is inserted into the through hole 310 of the roller 300 and pushes the bearings 350 provided on both sides outward so that the rollers and the caster frame do not generate clearance, So that the rolling property of the roller is improved.

The gap adjusting compression spring 500 is engaged with the through hole 310 of the roller 300 so that there is no gap between the through hole and the shaft on the outer circumferential surface of the shaft to absorb the load transmitted to the shaft when the load is generated, So that the stress on the load can be increased.

According to the present invention, the wheel structure for increasing the stress with respect to the load according to the present invention is constructed by fastening a tension spring to the outside of a shaft for fastening a roller to a caster, pushing a bearing fastened to both sides of the roller, There is no clearance, thereby increasing the stress on the load and improving the rolling property.

The terms and words used in the present specification and claims should not be construed to be limited to ordinary or dictionary meanings, but the inventor may appropriately define the concept of the term to describe its invention in the best way Can be interpreted as meaning and concept consistent with the technical idea of the present invention.

It should be noted that the embodiments described in this specification and the configurations shown in the drawings are merely preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It should be understood that various equivalents and modifications may be present.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 to 6, a pedestal 110 is fastened to a lower portion of a movable furniture or the like, a pedestal 130 to which the roller is fastened, And a bearing (170) that is coupled between the pedestal and the pedestal and between the pedestal and the pedestal; A roller 300 fastened to the caster frame by an axis to smoothly move movable furniture or the like; And a gap adjusting compression spring 500 fastened to the inside of the roller so as to prevent clearance between the caster frame and the roller and to prevent the roller from flowing when the roller rotates.

The roller 300 is formed with a through hole 310 through which the shaft 700 is inserted and in which the gap adjusting compression spring 500 is inserted and a bearing 350 is fastened to both sides of the through hole, A step 330 is formed.

The roller 30 is fastened to the caster frame by the shaft 700 and fixed to the lower part of the movable furniture or the like.

The gap adjusting compression spring 500 is inserted into the through hole 310 of the roller 300 so as to push the bearings 350 provided on both sides outward so that the roller and the caster frame do not generate a clearance.

That is, the inner peripheral surface of the gap adjusting compression spring 500 is formed to be the same as the outer peripheral surface of the shaft, and the outer peripheral surface of the gap adjusting compression spring 500 is formed smaller than the inner peripheral surface of the through hole 310, (500) are tightened to push the bearings to both sides without being rotated.

Accordingly, no flow occurs when the roller rotates, thereby improving the rolling property of the roller.

The gap adjusting compression spring 500 is engaged with the through hole 310 of the roller 300 so that there is no clearance between the through hole and the shaft on the outer circumferential surface of the shaft and absorbs a load transmitted to the shaft when a load is generated, So that the stress on the load can be increased.
