A fast detachable side wheel device, comprising: a first wheel cover, a second wheel cover, a wheel body, and a movable component. Firstly, wheel body is fixed in first receiving groove of second wheel cover as a replaceable component. Through positioning of a dovetail groove of first wheel cover and a dovetail tenon of second wheel cover, thus vibration, collision, or detachment of wheel body due to outside force can be avoided. Then, the movable component is used to control the positioning or detaching states between first wheel cover and second wheel cover, thus achieving fast and labor saving assembly and detachment of side wheels.
