Air damper used in glove box of automobile

摘要

An air damper suitably used in the glove box of an automobile comprises a cylinder having a first open end and a second end, a guide cap covering the first open end, and a piston movable in the cylinder. A compression coil spring is inserted in the cylinder between the piston and the guide cap. The coil spring forces the piston toward the second end of the cylinder in the free state. The piston has a hook piece, which is threaded with a spring. At least one end of the spring is taken out of the cylinder via the guide cap, and connected to the glove box. The guide cap has a stopper means projecting inside the coil spring and toward the piston. If the glove box is opened and the string is pulled out of the cylinder, the piston moves toward the guide cap. The piston then strikes the stopper means of the guide cap before the coil spring is fully compressed.
