A hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

A roller unit having an integrated fastening portion includes a supporting shaft fastened to a containing body or a containing main body that can slide and having first and second flanges formed in multi steps with different outer diameters, a rotating body rotatably fixed to a side of the supporting shaft, and a washer coupled to a side of the rotating body to surround and fix the second flange, thereby preventing separation of the supporting shaft and the rotating body. Therefore, it is possible to more conveniently combine the supporting shaft and the rotating body and to prevent separation of the supporting shaft and the rotating body, whereby is possible to improve various functions.

A snap lock device for securing a wheel assembly to an axle is provided. The snap lock device may be formed from one integral piece. The snap lock device may include a hubcap and a first and second clip extending from the hubcap. The first and second clips may include a spring, an engagement member, and an actuator. The spring may be directly coupled to the hubcap. The snap lock device may be installed in the wheel assembly by inserting the cap assembly in the wheel assembly such that the first and second clip are placed in two apertures of a wheel and the springs bias the engagement members toward a center of a bore defined in the wheel for receiving the axle. The snap lock device can allow for tool-less installation and removal of the axle.
