The invention provides an opening and closing device of a fairing of a railway vehicle and a front nose assembly, and belongs to the technical field of railway vehicles. The opening and closing devicecomprises a pivoting arm and a driving unit used for driving the pivoting arm to pivot relative to a base. The driving unit comprises a driving body and a driving rod. A first end of the driving rodenters the driving body, and the driving rod can move under the action of a driving force provided by the driving body so as to realize pivoting of the pivoting arm relative to the base. A second endof the driving rod is connected to the pivoting arm in a pivoted mode, and the driving body is installed on the base in a pivoted mode. The opening and closing device is good in reliability, and the pivoting arm is simple in structure, low in cost and easy to maintain.
