    摘要： A load cell is provided with protection against damage from overload. The load cell has a load receiving member, a main member and a load transmitting member. The main member has a movable portion, a fixed portion and a first parallel guiding member for connecting the fixed portion and the movable portion. The load transmitting member has a first mounting portion for mounting the load receiving member, a second mounting portion for mounting the movable portion and a parallel guiding member for connecting the first mounting portion to the second mounting portion. The first mounting portion is movable vertically relative to the second mounting portion when a load being applied on the first mounting portion. The load-transmitting member is a single piece. The load cell also has a stop portion for preventing the first mounting portion from further moving downwardly for overload protection.

    摘要： A parallel-guiding mechanism in accordance with the present invention comprises a load-receiving portion for receiving a load of a to be weighed object; a fixing portion including an end portion, an extending portion extending forwardly from the end portion and mounting portions extending forwardly from the extending portion, and parallel-guiding members connecting the load-receiving portion to the fixing portion. The mounting portions include a first mounting portion and a second mounting portion. A receiving space is formed between the first mounting portion, the second mounting portion and the extending portion for receiving at least a portion of the load-receiving portion. A containing space for receiving the extending portion is formed between the parallel-guiding members, the load-receiving portion and the end portion. The parallel-guiding members include an upper parallel-guiding member and a lower parallel-guiding member. The load-receiving portion, the fixing portion and the parallel-guiding members are formed integrally of one piece of solid material.
