Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To dispense with a bending work of a wire and miniaturize and highly density an electrical connection box by arranging a plurality of electric parts into a zigzag layout. SOLUTION: Fuses F as electric parts are arranged into a houstooth-check state. Branch wires B connected via a relay terminal 4 for the branch wire which is connected to one of connecting terminals of the fuses F are linearly arranged between adjoining fuses F. Therefore, the branch wires B are bent by a complicated bending work and eliminated any necessity of making a detour to avoid in other rows so as to be connected in a linear state. Because the bent parts of the branch wires B are eliminated, the interval between the fuses F can be arranged narrow so that the electrical connection box for storing the fuses F can be miniaturized and highly densified. The branch wires B branched from the main wire A via the fuses F are preferable to be arranged in parallel in the direction crossing with right angles with the main wire A.

Abstract: PURPOSE: To prevent dusts from dropping out of a suction port, by providing a dust receiving wall extending upward from the lower part of a suction chamber of a rotary-brush-type cleaner and by defining an upper port over the dust receiving wall to connect the suction chamber to a suction passage.  
     CONSTITUTION: The dust receiving wall 22 extends upward from the lower part of the suction chamber 8 so that the suction chamber 8 communicates with the suction passage 18 over the wall 22. A rotary brush 10 is revolved to scrape the floor by the brush 12 and  projection 13. Dusts, sand, pebbles, etc. are sucked into the suction port 1 of a sucking member 1 by sucking air flow. Then, the dusts etc. flow into the suction passage 18 through the suction chamber 8 and the port over the dust receiving wall 22 in accordance with the revolution of the brush 10. Since the dusts do not swirl in the suction chamber 8 but immediately flow into the suction passage 18, the dusts do not drop out of the suction port 9. Because the wall 22 is provided at the inlet side of the suction passage 18, the dusts do not drop out of the passage 18 even if the suction member 1 is tilted.
