Claims

[Scope of utility model registration request]

In an automatic avoidance righting device having a fixed support part and a movable support part, guide rods are vertically provided in at least three locations on one of the fixed support part and the movable support part, and a guide hole is opened in the other, and A fitting portion is formed in each of the guide rods and the guide hole so that they correspond to each other, and the contact surfaces of both of the fitting portions are formed in a tapered shape, so that the fitting portions of the guide rod and the guide hole are in contact with each other. A resilient member that elastically biases the fixed support part and the movable support part in the repulsive direction so that the contact surfaces are always in contact is provided between the fixed support part and the movable support part and between each of the adjacent guide rods. An automatic overload avoidance restoring device characterized in that an adjustment screw is provided in the same number or more than the guide rods and adjusts the resilient member by pressing from either the fixed support part or the movable support part, or both. .
