An annular groove is provided below the convex pillar at the front end of the spoke of the rim, and an O-shaped ring is fitted on the annular groove. The sleeve is hollow and dust and dirt enter. The effect of preventing and increasing the strength After assembling the hub and rim, the sleeve is installed between the hub and the rim to prevent dust and dirt from entering and protecting.The hub is provided with several spokes, on the spokes Is a wheel provided with a shock absorbing structure, characterized in that elastic parts are fixed and shock absorption can be performed after assembling the hub and the rim.

According to a second aspect of the present invention, there is provided a wheel having a shock absorbing structure, wherein the elastic part is a spring.

According to a third aspect of the present invention, there is provided a wheel having a shock absorbing structure, wherein the elastic part is a hydraulic cylinder.

According to a fourth aspect of the present invention, there is provided a wheel having an impact absorbing structure, wherein the elastic part is an air cylinder.

According to a fifth aspect of the present invention, there is provided a wheel having an impact absorbing structure, wherein the elastic part is a rubber body.

Since the shock absorbing structure is installed on the spokes of the wheels, the user moves on uneven terrain without using extra space for the structure and using hollow tires At the time, the vehicle can run comfortably due to the shock absorbing structure.

As shown in FIGS. 4, 5, and 6, the present invention mainly includes a hub 1, a rim 2, and a sleeve 3, and the hub 1 has a bearing 4 fixed at an axis, and several spokes 5 are provided. A recess 6 is provided inside the end of the spoke 5, and a spring 7 and a rubber body 8, which are elastic parts, are provided inside the recess 6. An annular groove 9 is provided on the front end surface of 5, and an O-shaped ring 10 is fitted on the annular groove 9.

The rim 2 includes a rim edge 11, a tire is provided on the rim edge 11, the rim 2 is provided with a spoke 13, and a convex pillar 14 is provided at a front end of the spoke 13. An annular groove 15 is provided at the lower part of the convex pillar 14 at the front end of the spoke 13 of the rim 2 so as to face the concave hole 6 provided inside the spoke 5 of the hub 1. An O-shaped ring 16 is fitted on the groove 15.

The sleeve 3 is hollow and has an effect of preventing the entry of dust and dirt and an effect of increasing the strength. After assembling the hub and the rim, a shock is absorbed by the spring 6 and the rubber body 8. The wheel has a practical and inventive shock absorbing structure that fits into the spokes 5 and 13 on both sides of the rim 1 and the rim 2 to prevent and protect dust and dirt from entering between them.

As shown in FIG. 7, an air cylinder 17 can be used as a component having elasticity inside the recess 6 of the spoke 5 of the hub 1. One end of the air cylinder 17 is fixed to the spoke 5 of the hub 1. The other end can be fixed to the spoke 13 of the rim 2 to absorb the impact.

As shown in FIG. 8, a hydraulic cylinder 18 can be used as a component having elasticity inside the recess 6 of the spoke 5 of the hub 1. One end of the hydraulic cylinder 18 is fixed to the spoke 5 of the hub 1. The other end can be fixed to the spoke 13 of the rim 2 to absorb the impact.
