A rotary locked structure of a door lock includes a tubular driving part and connected to a first knob. The driving part includes a restriction portion. An inner tube is received in the driving part and has a positioning portion located corresponding to the restriction portion to restrict rotational movement of the inner tube in the driving part. A restriction unit is formed axially in the inner periphery of the inner tube. A shaft includes a connection portion that includes a positioning unit located corresponding to the restriction unit to restrict rotational movement of the shaft in the inner tube. The driving part, the inner tube and the shaft are pre-assembled in factories. The inner tube and the shaft are not limited to be engaged in only one direction. The spindle and driving column can be directly connected to the inner tube and the shaft without rotating the inner tube and shaft.
