Abstract

A hard luggage case includes a cover portion and a body portion hinged to one side of the cover portion. The body portion is made of a rigid material for maintaining the luggage case in a fixed shape and providing sufficient supporting strength for carrying things, and includes a base section and an extension section telescopically fitted in the base section. An axially extendable structure is connected at two axially opposite ends to between the base section and the extension section, and is configured as a tubular member formed of a flexible material. A first fastening structure is correspondingly connected to along two facing ends of the base section and the extension section of the body portion; and a second fastening structure is correspondingly connected to along two facing ends of the cover portion and the extension section of the body portion.
