A trolley case capable of displaying weight in a static state allows the bracket fixing shaft not to offset in a radial direction through the configurations of a directional bearing and shaft liner, and allows a weighing transducer to sense the weight of a case body accurately by installing the weighing transducer on the directional bearing and fixing the weighing transducer to the upper end face of the bracket fixing shaft, thereby not causing a weight displaying value to change, realizing a static display, and thus giving users the convenience of use.
