To assemble liquid level indicator having an indicator frame, a contact holder, a resistor, a contact and a float in an automatic assembly system, the contact holder is formed into a crank shape having a first arm for holding the contact and a second arm for holding the float arm. Therefore, the contact holder can be assembled with the frame when moved in the direction the same as that along which the other parts are moved for assembly with the frame. Further, the contact is assembled when moved in the same direction, and the contact holder is temporarily fixed to the indicator frame for further facilitating the assembly work of the liquid level indicator.
