Abstract:
Provided herein is an infant wagon having improved convenience of use, wherein the infant wagon includes a front frame, a rear frame, a support frame, side frames, a front handle frame, and a rear handle frame, and is configured such that the axial distance between front wheels and rear wheels thereof is reduced, whereby it is possible to easily switch between a usage mode and a storage mode, such that the structure of the wagon wheel unit is simplified to reduce production costs, whereby it is possible to achieve product competitiveness, such that, when the wheels are worn or damaged, it is possible to easily replace the wheels, and such that the front wheels and the rear wheels are compatible with each other and are interchangeable.

Claim (Index 9):
The wagon according to  claim 1 , wherein the first rear wheel drive assembly comprises:\n rear wheel fixing frames fitted on inner rear wheel support frames, disposed at the left and right lower ends of the rear frame, each of the rear wheel fixing frames having an elliptical cylinder shape, a rear wheel detachment grip being coupled to a rear of each of the rear wheel fixing frames, each of the rear wheel fixing frames being configured to support a rear end of a rear wheel elastic spring mounted under the rear wheel fixing frame inside the rear wheel fixing frame, the rear wheel fixing frames being axially coupled to rear wheel shock absorption frames, which are located at a lower end thereof; rear wheel shock absorption frames, each of which is formed in a bracket shape in section, each of the rear wheel shock absorption frames being coupled to a lower end of a corresponding rear wheel fixing frame, each of the rear wheel shock absorption frames being provided at one side of a rear thereof with a rear wheel fixing shaft axially coupled to the corresponding rear wheel fixing frame, each of the rear wheel shock absorption frames being configured to support the rear wheel elastic spring connected to a rear wheel rotating shaft disposed at one side of a front of the rear wheel shock absorption frame and axially coupled to a rear wheel brake assembly, the rear wheel brake assembly being coupled to an inside of each of the rear wheel shock absorption frames, each of the rear wheels being coupled to an outside of a corresponding rear wheel shock absorption frame; a rear wheel brake assembly configured such that a rod-shaped brake rotating shaft is horizontally coupled to an inside of each of the rear wheel shock absorption frames, the rear wheel brake assembly being provided at a middle thereof with a brake pad which has a rectangular surface to control rotation of the rear wheels; and rear wheels configured to be rotated in a state in which the left and the right rotating shafts of the rear wheels are coupled to the respective rotating shafts of the rear wheel shock absorption frames in order to provide force necessary to move a rear part of the wagon.
