An in-vehicle input device includes a mechanism to detect the approach direction of a finger and tilt a touch panel in the right-left direction. The actuator is movable in at least a tracking direction and a focus direction. An arrangement of the spouting part and the particle collecting face with respect to each other is adapted to generate, during operation of the device, a rotating flow pattern in the fluid that is present in the chamber under the influence of the flow of the fluid to be filtered, whereby particles can be blown away from the particle collecting face. To alter the unbalancing limit, the characteristic curve is altered in dependence on a correction value. The separated portion is separated from the covers and includes the device-side holding portions.
