Dear Takeshi,
For a PDB fitted to a map, just use "File... Save PDB" in the menu  
and make sure to choose the option to "save relative to" the map model.

For saving a map fitted to another map, you could just save the  
Chimera session, which will preserve the orientations of the  
different models.  However, if you want to save a map file to use in  
other programs, it is necessary to resample the map that you fit on  
the grid of the map you fit into.  Resampling interpolates data  
values and can degrade map quality.

You can create a resampled map with the "vop" command and then save  
that new map with the Volume Viewer dialog or "volume" command, as  
described in this previous post:

More about "vop":

I hope this helps,
