Abstract: A collapsible step bar comprising a step bar body, a bracket, a first link, a second link and a pin is provided. The step bar body comprises a first shaft and a second shaft in a front end of the step bar body. The bracket is disposed adjacent the step bar body. The first link comprises a first end and a second end, and the second link comprises a first end and a second end respectively. Both the first ends of the first link and the second link are pivotably disposed on the bracket, and both the second ends of the first link and the second link are pivotably disposed on the first shaft and the second shaft of the step bar body respectively. The pin pivotably connects to the bracket and the first link for control of a rotation of the first link, such that the step bar body is rotatable into a closed state or an opened state.
