Abstract: An information providing device includes: a vehicle condition detector for detecting a vehicle condition; a support information generating element for generating support information for a driver; and a tactile sensibility notification element in a steering wheel for notifying the support information to the driver. The steering wheel includes a wheel element having a base, a movable portion and a driving unit. The movable portion is relatively movable with respect to the base. The driving unit drives the movable portion according to the support information. The movable portion and the driving unit provide the tactile sensibility notification element. Movement of the movable portion provides notification of the support information.

Abstract: A printed board has a board, an electrically insulative membrane, formed on the board, and an electrically conductive membrane, formed on the electrically insulative membrane, in its area where a control circuit, including a CPU and etc., is installed. The electrically conductive membrane is electrically connected with ground patterns of a wiring pattern. Accordingly, ground connections at the control circuit are sufficiently performed. Therefore, even though ground connections in an area other than the control circuit are not sufficiently performed, a magnetic noise is prevented from being generated in a loop-shaped electricity supply line passing through a CPU and etc. Consequently, noises in printed board can be effectively reduced.
