<p>PROBLEM TO BE SOLVED: To obtain an electrical junction box by which the influence of design tolerances of wiring boards is minimized to make protruding lengths of a plurality of connection terminals approximately uniform and electronical components can be satisfactorily connected to the connection terminals. SOLUTION: Wiring boards 7-10 are housed in layers in a lower ease 3. Supporting protrusions 11-13 with shapes of stairs are formed on a plurality of corners of the lower case 3. The heights of the supporting protrusions 11-13 are made to correspond to the arrangement heights of the wiring boards 8-10 from the bottom wall 3a of the lower case 3. Notches 35-37 are formed in the corners of the wiring boards 7-9 and the supporting protrusions 11-13 for all the wiring boards 8-10 above the boards 7-9 can pass through the notches 35-37. When the plurality of wiring boards 7-10 are housed in the lower case 3, the wiring board 7 is supported by the bottom wall 3a, the wiring board 8 is supported by the supporting protrusions 11, the wiring board 9 is supported by the supporting protrusions 12 and the wiring board 10 is supported by the supporting protrusions 13.</p> |
