Abstract: A mail terminal has a tab section formed by bending and folding back a plate-like base material on itself. The tab section has a first flat plate section, a fold section which is formed at a side end of the first flat plate section by bending, and a second flat plate section which is extended from a side end of the fold section and which is superposed on the first flat plate section. At least one of the first flat plate section and the second flat plate section has a depressedly deformed section provided at the side end thereof which is located on the side opposite the fold section. The depressedly deformed section is depressed on the outer surface side and protrudes on the inner surface side.

Abstract: In an assembling structure of an illumination unit, a light emitting component is mounted on a circuit board, and a housing accommodates the circuit board on which the light emitting component is mounted. A housing light-emitting part is formed at the housing, and transmits light emitted from the light emitting component. A housing light-blocking part is formed at the housing around the housing light-emitting part, and blocks the light emitted from the light emitting component. The housing is configured to be assembled into an assembled subject. The housing includes an exposed surface being a plane and including an outer surface of the housing light-emitting part and an outer surface of the housing light-blocking part are provided. The assembled subject includes a slit which forms an opening through which the exposed surface of the housing is exposed.
