  • Inhibitor switch device having an operating lever with a strength adjusting portion
    Patent number: 5828022
    Abstract: An inhibitor switch device having an operating lever 9 equipped with a strength adjusting portion 96 near the rotating axle. The strength adjusting portion 96 has a mass which can be adjusted by using a nested-type metal molding. The strength adjusting portion 96 allows the operating lever 9 to be set to a suitable strength so that the operating lever 9 breaks when an abnormal external force is applied. Also, when an abnormal external force is applied, the strength adjusting portion 96 prevents the spread of breakage to the rotating axle, and allows easy detection of defective products by an external check of the strength adjusting portion. In addition, the strength adjusting portion allows fine adjustment of the operating lever 9 to a suitable strength during formation thereof, thereby preventing the strength adjusting portion from being broken under regular external forces.
