Apparatus is provided for controlling the positioning of an awning relative to a recreational vehicle. The apparatus includes a rotary shaft and a roller mounted on the shaft in concentric relationship with the shaft for rotation with the shaft. An annular cap and a brake member are also mounted on the shaft at one end of the shaft in concentric relationship with the shaft. The brake member may be disposed within the cap. A control member such as a eccentric is disposed on the shaft in eccentric relationship with the cap and is rotatable to first, second and third positions. The eccentric is disposed in the first position in cooperative relationship with the brake member to provide for a rotation of the brake member in a first direction for winding the awning on the roller and to inhibit the brake member against rotation in a second direction for unwinding the awning from the roller. The eccentric is disposed in the second position in cooperative relationship with the brake member to provide for a rotation of the brake member in the second direction for unwinding the awning from the roller and to inhibit the brake member from rotating in the first direction. The eccentric may be disposed in the third position in displaced relationship from the brake member to provide for a rotation of the brake member in the first and second directions.
