  • Publication number: 20230093177
    Abstract: An operation device includes a first displacement portion that is displaceable by being operated by an occupant of a vehicle, a second displacement portion supported at the first displacement portion, and an extension/retraction locking portion. The second displacement portion is displaceable with respect to the first displacement portion by being operated by an occupant of the vehicle. In a state in which the first displacement portion is positioned at a first position, the extension/retraction locking portion restricts displacement of the second displacement portion with respect to the first displacement portion. In a state in which the first displacement portion is positioned at a second position, the extension/retraction locking portion permits displacement of the second displacement portion with respect to the first displacement portion.

  • Patent number: 8324853
    Abstract: A vehicle wiper controller includes a wiper drive circuit which drives a wiper. An operation switch is manipulated in a plurality of manipulation directions or to a plurality of operation mode positions when a manipulation force is applied thereto. A wiper operation control unit electronically controls the operation of the wiper and sets the wiper to an operation mode corresponding to the manipulation of the operation switch. A control signal hold circuit, discrete from the wiper operation control unit, transmits a control signal to the wiper drive circuit when the operation switch is manipulated in a predetermined first manipulation direction or when the operation switch is manipulated to a predetermined first operation mode position. The control signal hold circuit sets a hold state for holding the transmission state of the control signal.
