PROBLEM TO BE SOLVED: To provide packing for ventilation, which is used for underfloor ventilation between a foundation of a building and a sill thereof, and which achieves cost reduction and an improvement in the earthquake resistance of an anchor bolt by enhancing constructibility. SOLUTION: When the packing for ventilation is installed on a continuous footing, the multi-packing can be freely assembled and connected to each other without use of a tool, irrespective of whether the building is a new one or a reformed one, and irrespective of the length of the foundation and the width of the sill. Structurally, the displaced anchor bolt can be easily inserted into an insertion hole which is normally expanded or expanded in such a manner as to be turned upside down. The height of the packing is set equal in dimension to/or smaller dimension than a wire diameter of an M12 anchor bolt, so that the earthquake-resisting strength of the anchor bolt can be enhanced, and the rat-proof function of the packing is also exerted.
