To provide a respiratory mask device for harmful gas removing air for a harmful gas such as a carbon dioxide gas that is generated under a closed space environment such as when going aboard a vessel, a construction site and subsurface construction sites.SOLUTION: There is provided a respiratory mask device for harmful gas removing air for harmful gas such as carbon dioxide. Right and left side faces in the lower half of a respiratory mask face are attached to right and left base parts of right and left front side support rod parts and right and left rear side support rod parts of right and left V-shaped support rod parts of a balance shape-retaining plate respectively, and the right and left base parts are supported by a connection plate part or an equivalent member in an integrated manner. Lower end parts of right and left front side elastic suspension bands, and right and left rear side elastic suspension bands disposed on right and left side faces of a cap type support band that a wearer puts on separately in the front and back are detachably connected to right and left tip parts of the right and left V-shaped support rod parts respectively.
