PURPOSE: A clearance structure for the adsorption of a wall panel for tongue and groove joint using a clearance regulating attachment is provided to adsorb volatile organic compounds to an adsorption material located at the rear of a wood panel. CONSTITUTION: A clearance structure for the adsorption of a wall panel for tongue and groove joint using a clearance regulating attachment is comprised as follows. An activated carbon board is attached to the surface of a wall. Wood panels are installed on the top of the activated carbon board using clearance regulating attachments. The sum of the thicknesses of the wood panels connected through tongue and groove joint using the clearance regulating attachments is the same as the thickness of a single wood panel which does not use the clearance regulating attachments. When the clearance regulating attachments are installed, the clearance structure is automatically formed in a portion where does not have the clearance regulating attachments.
