Overload prevention is important for a force sensor in order to avoid fatal damage due to unexpected external force. Until now, most of the proposed mechanisms for this purpose prevent the damage to the sensor by using a screw and a straight pin. Few reports on the utility of these mechanisms have been published. In our previous work, we proposed a unidirectional force sensor based on an H-slit type parallel beam structure. The H-slit beam structure is a part of a force sensor and it can perform as an overload prevention mechanism without any additional mechanical parts. In this paper, we verify the utility of the H-slit type beam based overload prevention mechanism. Besides, based on the verification result, this paper proposes a new slit type beam overload prevention mechanism.
