Description of the invention: [Technical field to which the invention pertains] The present invention relates to a caster, in particular to a distance that grows under the glaze under the glaze, and the relative age of the straight shaft and the components it wears. The weight can be transferred to the core, as well as the force of the lower side of the straight sleeve on the side of the rotating side, and the length of the office chair casters. [Prior Art] According to the casters (1) used in the seats currently on the market (see the seventh figure), which include the caster body (10), the shaft (11), the lower cover (12) and the rolling elements (1) ), (the work piece; wherein the shaft (ii) has a body-formed upper cover (丄: 〇), which is combined with the caster body (1〇) by the bottom lower cover (12), on the shaft (^ Between the upper cover (1 1 0) and the top surface of the caster body (1 〇), a full-circle rolling member (work 3) is provided, and is also disposed between the lower cover (1 2) and the bottom surface of the caster body (1 ◦) There is a full circle of rolling elements (丄4), by which the rolling wheels (13) and (14) can smoothly rotate the casters (丄); such casters (丄), after use, have the following disadvantages : 1. The distance between the upper cover (ii 〇) and the lower cover (丄2) of the caster (1) is short, so the weight of the shaft (1 1) and its caster body (1 〇) can be relatively reduced. It is easy to damage under the long-term load. Second, because the distance between the upper cover (i丄〇) and the lower cover (丄2) of the caster (1) is short, the lower part of the shaft (11) can bear the burden. The turning force is low. Under long-term use, the shaft (completed) is prone to loosening and shaking. 3. The caster (1) is made of metal because the components are made of metal. In view of this, the present inventors have developed a new "office chair caster" based on years of experience in the industry and multi-party testing. [Invention] The office chair caster of the present invention The purpose of the design is to increase the distance between the lower part of the straight axis and the lower part of the straight shaft and the components it is worn to increase the bearing load of the caster and the tolerance of the rotating side force, thereby prolonging the use of the caster.
