Abstract: A lead component holder includes a plurality of supporting portions each supporting a lead component at a position distant from a component mounting surface of a substrate, and at least one coupling member coupling the adjacent supporting portions at a position distant from the component mounting surface. An electronic device includes the substrate, the lead component holder, and an electronic component mounted to the substrate located below the coupling member.

Abstract: An electric motor controller with a screw terminal block including: a terminal fitting connected with a solderless terminal having a crimping portion crimped to wire cores of an electrical wire; a plate-shaped square washer having a cut-out portion in at least one edge thereof, the cut-out portion for avoiding interference with the crimping portion of the solderless terminal or the wire cores projecting from the crimping portion to an end of the electrical wire; and a terminal screw fixing the solderless terminal between the square washer and the terminal fitting.
