Awning apparatus for travel trailers, mobile homes, and the like for canopy awnings of the type having a canopy attached at a fixed rail on the vehicle and at a wind-up roller bar. The roller bar includes springs for asserting wind-up tension on the canopy at all times such that movement of the roller bar from the canopy in-use position spaced from the vehicle to a storage position adjacent the vehicle is accompanied by an automatic wind-up of the canopy around the roller bar. A four point suspension system is provided for supporting the roller bar which includes side arms engageable with respective opposite ends of the roller bar and rafter arms engageable with the roller bar at positions intermediate the ends of the roller bar. To accommodate adjustment and connection of the rafter bars, the roller bar is provided with a slot engageable with an enlarged ball end portion of the rafter bars. The rafter bars are pivotally connected at the vehicle at a position adjacent the in-use storage position of the side arm bars. At the mounting rail on the vehicle, saddle brackets are provided for cradling opposite end portions of the roller bar when in the storage position, which saddle bars include a detent bulge engageable in radially facing recesses on the roller bar to automatically prevent rotation of the roller bar when it is clamped in the storage position forced downwardly against the saddle bar. The roller bar is provided with removable end caps for accommodating access to the internal wind-up springs, which end caps include slots in alignment with slots in the roller bar for accommodating exchange of the canopy without requiring removal of the end caps.
