ABSTRACT:
An object separating apparatus uses gas and has a hollow housing with a closed end connected to a first object, and an opened end. An axially movable cylinder is installed at an inner space of the housing and a piston assembly is coupled to the cylinder and connected to a second object at an outer end. A fixing portion between the housing and the cylinder and the piston assembly fixes the cylinder and the piston assembly into the housing. A gas generator communicates with the inner space, wherein when the gas generator is operated, the gas generator pressurizes the cylinder to release the cylinder from the piston assembly and to separate the cylinder and the piston assembly from the housing.
