Roof console device for vehicle

A roof console device for a vehicle is formed by fixing a console housing to a lower face of a front portion of a vehicle roof, inserting from below a roof module into a housing portion formed in the console housing, and joining them by concavo-convex engagement. A backward facing wall face of the roof module and a forward facing wall face of the console housing oppose each other across a gap. A recess portion is formed in one of the backward facing and forward facing wall faces, and a projecting portion is formed on the other. Therefore, even if the concavo-convex engagement is disengaged due to an impact of a secondary collision, the console housing moves and the recess and projecting portions are fitted together to thus allow the roof module to be retained by the console housing, thereby preventing the roof module from falling from the console housing.
