Claims

[Scope of utility model registration request]

A case molded from synthetic resin and a first
A fixed contact forming a terminal, a bimetal to which a movable contact that can be brought into contact with and separated from the fixed contact is fixed to one end, and the other end of the bimetal is fixed and pulled out of the case to form a second terminal. A conductor to be formed, a movable piece that engages with both sides of the central part of the bimetal, is slidably guided in the case in a direction orthogonal to the bimetal, and has a screw hole on one end surface, and is inverted to the fixed part of the case. a leaf spring that is supported so that it can be supported and has a concave free end coaxially opposed to the screw hole; An overcurrent protector comprising: a tapered threaded rod that can be moved forward and backward from a peephole; and a reset button that is axially guided in the case and can be engaged with the center portion of the bimetal.
