An upper panel section includes an inserting hole into which a tip of a longitudinal-type equipment-side connector that is mounted on a PCB board of an electrical device at right angles and includes a spring section formed on its lateral surface is inserted. A foot section supports the upper panel section on the PCB. An inner circumference of the inserting hole has a shape surrounding substantially an entire circumference of the tip of the equipment-side connector. The foot section is provided at a position that opens up the lateral surface of the longitudinal-type equipment-side connector on which the spring section of the equipment-side connector is formed.
