Abstract: When receiving no reverse state signal, which indicates that a vehicle is in reverse, a wash control circuit allows the actuation of the wiper motor by the interlocking operation and retains a changeover valve device on the side of the window washing nozzle. When receiving a reverse state signal, the wash control circuit switches the changeover valve device from the window washing nozzle to a camera washing nozzle and inhibits the actuation of the wiper motor by the interlocking operation.

Abstract: A wheel for an automobile is configured in such a manner that the wheel disc comprises an outer peripheral ring section having protrusions and recesses, the outer peripheral ring section being formed by continuously and alternately forming circular arc-shaped contact sections and contactless protrusion sections along the circumferential direction of the wheel, the circular arc-shaped contact sections being in contact with and welded to the bent peripheral section of the wheel rim, the contactless protrusion sections protruding further toward the front side than the circular arc-shaped contact sections and separating from the bent peripheral section. Welded sections at which the circular arc-shaped contact sections and the bent peripheral sections are welded together are intermittently arranged in the circumferential direction of the wheel.
