Abstract: A retractable travel bag handle assembly includes a retractable handle moved in and out of two cylindrical casings fixed to the inside of a travel bag, two socket caps mounted on the travel bag and connected to the cylindrical casings to prevent disconnection of the retractable handle from the cylindrical casings, wherein the retractable handle consists of two sleeves respectively coupled to the cylindrical casings by movable couplings and a substantially U-shaped handlebar having two opposite ends moved in and out of the sleeves, each movable coupling including a base block having two square projections at two opposite sides moved in two hollow side wings along the cylindrical casings, and a connecting rod having one end fixedly connected to one sleeve and an opposite end pivotably connected to the base block by a pivot for allowing the retractable handle to be turned relative to the travel bag to change the steering direction.
