A technique of preventing permeation of liquid and dust to electronic parts within a housing of an input device for an in-vehicle device. An input device of an in-vehicle device comprises a housing that stores a substrate and an operating member that passes through the housing from a side of the substrate and is exposed to outside. A first drain hole is formed in the housing at a position corresponding to a gap between the housing and the operating member. The first drain hole is coupled with a drainpipe, which passes through the substrate to the back side of the substrate.
